Vložit
- čas přidán 20. 08. 2024
- This chemistry video tutorial explains how to find the empirical formula given the mass in grams or from the percent composition of each element in a compound. If you're given the mass percent, you can simply treat it as if you were given the mass in grams. This video explains how to find the molecular formula given the molar mass of the compound. You can do this once you have the empirical formula. This video explains all of it. It has plenty of practice problems and examples for you to master this lesson.

Let's all agree -> This Man is saving our chemistry grades!
Yh if most of his videos weren’t long af
Ikr, this man be turnin ma I's into A's (In Canada, we use I)
fr my grade was awful before this and my teacher was the least helpful

I always love scrolling through comments of videos like this and seeing "You're 100x more competent than all my professors" or "you taught something in 11 min that my prof couldn't teach in one semester"
its true though ive been trying to understand this for weeks and i get it in 11 minutes
You probably have received a lot of comments like this but I'd just like to say that your voice is so calming and reassuring that it makes Chemistry feel like it's not that bad at all and is just a bunch of equations that can be broken down to something simpler. Thank you.
you're my hero
I had multiple mental breakdowns and no matter what video I watched I didn't understand. As an IB student who has my exam in 3 days you are a god
I hope you become a professor you have no idea the difference you make in peoples lives. I was really struggling I mean to the point of tears because my professor rushes through the materials and doesn't care at all for the students ability to learn and I've been suffering along with my classmates but to think that somebody like you can make such a topic so simple! I hope you read this and keep doing what you do I subscribed and you are really making a difference to me and soo many other ppl Thank You
Fr ive been gettin F's in chemistry I basically gave up.
Until this man shed light on my soul and Motivated me to go on.
Poof. That’s an L

3:01 why is the decimal digit of C from H and O different?
Agreeedddd I would cry because I didnt know what to do anymore this semester cause I would spend so much time studying and failing because my professor only has 50 minutes to teach us and she goes way too fast.
@@gionadvincula5811
It is because the numerators solves the denominators at after two decimal point while others take it so.
who else watching this hours before a chemistry midterm?
Above The King Me!
lol me
My exam’s in 2 days hahah, lets goooo
MiyukiYE same its tomorrow now
mine is in an hour LMAOO
I have extremely high aspirations to become an Orthodontist, I still have a long way to goal and im currently making my way towards dental school, but your videos are incredible, you do a phenomenal job teaching and having people practice problems alongside you, you've changed the lives of millions and I, along with all of your viewers are forever grateful for that. Thank you once again, you deserve 100 million subscribers for the beauty of your work.
When I needed to learn an entire Chemistry Unit in 15 minutes, this guy clutched for me.
not only is your voice sooo soothing but your explanation was also perfect 💖
And I love his handwriting, it’s so satisfying to watch!
This man helped me from failing PreAP chem to getting straight As on it, can’t thank u enough
Which grade are you
Who else is watching this a night before their chemistry exam 😂
Nah bro, I'm watching this an *HOUR* before the exam
My exam is in 04hrs😭
me
At my bus stop RN watching it😭😭
20 mins b4 😂
You're honestly a life saver. My professor won't teach us anything. I know it's online but she sucks at explaining things. Your videos have literally kept me teetering between a B and C in this impossible class. Thank you so much! I'm also saving your stuff for studying for the MCAT!
Edited to add. She's making us use a book that's about 10 years old and the atomic weights are all out dated :)
Big oof
Better than my chemistry teacher!
제니김
By far
PERIOD
Same
Better than all of our chemistry teachers
can someone tell me why became 100 grams it cllearly is 138
my chemistry teacher never even shows up to class you’re a life saver!
🤣😂
Studying hours before a test gang, where u at
Dizzy_Mab hahahah right here
My exam is in 9 hours
Mine is in 8 hours lets go
2 minutes lolll
right here
studying during test gang
my teacher didn’t even tell us to divide by the smallest mole..... why is he getting paid💀💀💀
you dont have too, but its the easiest pathway
Exactly
Because he has a degree
You don’t have to it’s just easier, the teacher doesn’t always have to teach you the easier way lol
@@dcutestluv9023 thats the thing my school sucks my teacher has a degree in human anatomy but my school thought it would be fine but hes an awful teacher
Wow I finally Understand this 19 hours before my exam
Good for you!
😂 same
I want to add my own portion of praise to your content. You sir, deserve a metal for assisting everyone with Chemistry!
And to everyone else studying, I wish you all the best of luck!
Completely agree
Wow, it’s that simple:
My teacher can’t explain anything lol
сестракофе ong bro
Lol same dude
Samee
@@shanewooden7370 imagine having a teacher
-this post was made by teacher on maternity gang
Mine rambles on and on getting off topic then zooming through the slides. This CZcams teacher plus my textbook are getting me through chem 1
This dude has no idea that his videos are the reason for my grades in chemistry. God bless you
Imma go ahead and tell Broward College to send you a check because you taught me in less than 5 min what my horrible chemistry teacher couldn't teach me in 3 hours. smh
Fatigue Alexander I thought I was the only one who had that thought
Bro I’m in Broward rn 😂😂
It honestly seems pretty straightforward and just shows that you don't pay attention in class?
crusader_x0 you sound like someone who's never had a truly bad teacher lmao
broward gang
I just want you to know that, in less than an hour, you've taught me more than my chemistry professor did in an entire semester. Thank you so much for the hard work.
Your videos changed my life. I didn't flunk out of high school. I stopped selling drugs and began learning different chemical reactions. You made me become the person who I am. When I'm on a plane I remember the soaring heights I have achieved thanks to you. I will never forget you, The Organic Chemistry Tutor.
I can't believe i pay hundreds of dollars to have some professor give me an hour long PowerPoint presentation with zero multimedia skill and always end up on your videos having you explain everything to me for free in 10 minutes. Thank you so much for your service.
I cannot thank you enough for the easy and simple walk-through that wasn't done in my class
Im falling in love with chemistry more... and your voice 😂😂😂
JESUS loves you so much
@@campalovesjesus5705 thank you.
this video is so helpful. i couldn’t learn this in one semester with my professor, but with you i learned it in 11 mins. thank you!
I learned in like 11minutes than my whole 45minute chemistry class .... Truly the Best Chemistry Teacher ever ❤
I finally learnt this in 10 mins while i couldn't understand anything my teacher was saying for an hour, ugh much love
these videos are single handedly getting my through my chemo class. Bless you
Dude. I cannot stress this enough. I spent the past 3 months trying to figure this out and my professor wouldnt help me not to mention her notes make no sense. Thank you from the bottom of my heart seriously.
Wow I was literally so lost during my lab when my professor was explaining this and after seeing this video you truly realize how something so simple can be explained to be so complex. Thank you so much for this you're a life saver!
Who else is watching in 2020 lockdown when teachers sucks and just sleep during online classes 🖑
my teacher doesnt suck but i keep falling asleep becasue shes always my last class
Yes except 2021
Six minutes into your video and I have a firm concept of what my professor attempted to teach for a week. I am a big fan. I don't even watch my professor's videos anymore, straight to this channel. Thank you!!
wow i have a chem test tmmrw and this video was posted 5 years ago i swear this channel has everything for about anything for school
You made studying for my chemistry and calculus trimester a million times easier. Thank you so much. I’ve been relying on you for the past two years to learn math and science. Keep up the good work!
Seriously without u I would not be a honor student. I am really gratified out of gratification. Thank u so much u are the best actually just after my chemistry teacher😊❤.
i want to say something about you ,OMG you are so educated , smart person u know everything inside out therefor this world deserve a person like you
You are a legend from the people coming from England, thank you for teaching us a 1 hour lesson in 10 mins
y'all i love my chem teacher honnestly, but this is so much fricking easier to understand
Thank you so much! All your videos are so easy to follow and really make sense of all the things I can’t understand in my fast paced class, thanks again!
Watched this and now i totally understand the how to calculate these. I've got my IGCSE Chemistry exam on Monday and this definitely helped me feel more confident!!!
If you aren't a professor, you've missed your calling. This has helped me tremendously!
Writing my physics paper tomorrow for 10th grade, this helped me out so much🙏
And good luck to all future viewers
This video helped me understand the way to calculate empirical formula so much better! Thank you so much!
Thank you a lot honestly some tutors make you pay to learn thank you for being kind and making CZcams channels like this. I’m not a science student at all and this really helped me understand. You can really understand anything if your taught the right way. Thank you again
This is the best explanation i would get, I'm literally writing my final paper tomorrow and i get this now. Thank you so much 😊
thank you for this, I was sooooo problematic coz I was absent when my teacher discussed this and today is the SEMI FINALS of my chem class likeeee HOW CAN I ANSWER THOSE PAPERRSS --but gladly I found your video. 😊 THANK YOU SOOO MUCH FOR YOUR HELP! you're an angel 💜😸
literally have a test in this in period 5...... i’m in period 2 watching this 😭😭
on god this mans is saving me rn. my chem teacher gives us like 2 hour long zoom recording lectures where she literally goes on hour long tangents, and I finish the lecture remembering exactly nothing. but now I just see what the lecture is on, and watch these vids to learn the material. bro Is saving me hours of time
life saver and a 1000 times better than school teachers
I don’t know who could give this video a dislike
Omgeee this was abig help and tomorrows gonna be my exam😊 GOSH INEEDED THIS THANK UUUUU
Professor Organic Chemistry Tutor, thank you for using examples to Compute the Empirical and Molecular Formula in AP/General Chemistry. The simplest (empirical) formula of a compound gives the simplest whole number ratio between the number of atoms of different elements in a compound. The molecular formula indicates the number of atoms of each type in a molecule. This is how Chemistry books breakdown the material presented in the video. This is an error free video/lecture on CZcams TV with the Organic Chemistry Tutor.
end year exams 🔥🔥
Same😂
wow i love learning a concept in 10 minutes when my professor spent 2 days trying to teach it to us...
@@Choco_krispies i dont care we all afree that learning online from youtube is much bettter
Love u
Do you like indians

Bro explained empirical formulas better in 11 minutes than my professor explained in a whole 2 hours
I learned more from this video in five minutes than from my teacher in 2 weeks.
ok so i feel like the general theme of this whole comment section is that most chemistry teachers just can’t teach.... yikes it’s not just mine. 😬
most STEM teachers in general cannot teach. Praise CZcams University.
Same
Got my boards tomorrow, really helpful. Thank you so much.
I basically use this professor for all my science subjects ❤
this was so helpful im watching this 3 hours before the exam 💀💀
The O-chem tutor + Sal Khan....... Name a better duo I'll wait.
you literally taught me my first semester of general chemistry, my prof wasnt there for the entirety of half the semester.
Hello, Organic chemistry tutor. I do really appreciate your videos. These helps me alot when I'm studying my major Subjects. Thank you❤️
i love this man he saves my grades man
bro you are the best I totally understand this topic now. It took my teacher weeks and I still didn't understand but it only took ten minutes to understand as you taught. Thanks a million
Wow man now I understand better how to calculate the empirical formula and the molecular formula 💯I'm so sure that I'm gonna pass my physics tomorrow with an A+🥳🙏
Don’t forget the sig figs for your answer👍
wow .. u made it so easy dude ... i feel like i knew this thing my whole life but was waiting for someone like u to explore it
HahHa dude
thank you so much i have a final exam tmr and i’m trying to learn everything that my horrible teacher couldn’t explain to me in these past couple months in one night and i gave it a go with some practice problems from previous homework as well as your second example in one try and i got it! your a LIFE SAVER ♥️!
This guy single-handedly solves all chemistry doubts. real GOAT
Learned this in sophomore year high school and then had to take a chem class my first year of college. Fml
Please do you have any written book 📚📚 for chemistry
Please do you have any written book 📚📚 for chemistry
This channel saved two of my chem exams xD
Man you teach better than most of the Chemistry teachers out there , Thanks you are a lifesaver
Im in 9th grade and unlike everyone our school doesnt even teach us anything they just give us the module and expect us to understand the topic so you're really a lifesaver!
Thank you very much sir.
Sir make an another video for energy level diagrams
wow this video literally made me go OHHH every second
yesterday i watched other video about this topic provided by our school and I got wrong answer, then now I answered it again using this guide and it was RIGHT!!! WHOO THANK YOU
Man you're a life saver😢this was the best 11 minutes of my life..….2 hours with my lecturer was not making sense 😊
this taught me more than my actual teacher
Came to UF for an education but wait until after class to look up these videos in order to learn, sick
CZcams tutorials explain more in 10 minutes than any teacher in 5 lessons
What my teacher couldn’t teach in an hour and a half. This guy did it in 4 mins
Am watching this because I have chemistry exam tomorrow🚶
sameeeeeeee
how i can donate you ?.....where is donation url ?

god bless you sir
when converting into mole, how many decimal points should I consider?
Coming late but not too late. Thank you sir . You made me chemistry easy subject
My teacher couldn't quite explain the Empirical Formula properly, I sort of managed to understand it but this defininitely clarifies it. Your videos are great in general.
Legends can hear sound of calculator 😅
Everyone can
4:59 where did that cane from?
its the molar mass
I don't normally drop likes on videos, but this one.... this one is special, this channel is special.
You're amazing!!! I've been so stressed because I was behind on the material and as usual you saved the day!! You teach better than my professor lol. THANK YOU SOOOOO MUCH. We appreciate you
Thank u
lolo bon
sir greppy bery bad wasting our time man
true
Thank god people like you exist bro
I feel like my professors move so fast and I have a hard time keeping up. but here sometimes I don't even have to pause your videos because you explain everything so thoroughly! thank you so much, you're savin my chem life :D
