i'm going to cry. thank you so much. i've never understood this even though ive gotten all my teachers to explain it - but you've just helped me so much. you're amazing. thank you!!!!
Brilliant video for me, as a self study student. Although the guys is like story telling and his presentation isn't like textbook, this video just helps me remember by understanding and I don't have to just cram the calculation methods into my head
This really made sense to me thank you and a great way to remember the calculations. I used the method for an AQA GCSE practice question but it seems they didn't use the balanced equation given in the question but the unbalanced equation. I'm confused now.....is it different for different courses?
I unfortunately didn’t understand the last bit Like the 2nd worked ex after the part where you got moles of the reactant Could you somehow make the explanation a bit simpler
10:58 , we had ( Fe2 ) in the reactant then, we had ( 2Fe ) in the product, doesn't that make a difference? { I didn't even know what computational chemistry was, this is my introduction to it. So, forgive me if this is a silly question... )
in the case of balancing equations it does not make a difference as the no. of Fe going in is the same as the number of Fe going out. Also dont ever ask for an apology if you want to know something everyone had to start somewhere
isn't there a simpler way. I just did iron relative mass times 2 and divided it by the relative atomic mass of the Iron oxide and times it by 300 and I got 210 g
Just a small query, for the last bit when we calculate the mass of Iron using the mole ratio, would the RAM not be 112 instead of 56 because on the formula it says “2Fe” so would you not multiply 56 by 2?
sorry this is so late BUT noooo! as basically you would only multiply by 2 if it is the subscript (e.g Fe2) hope that helps :) the reasoning is that some elements are di-atomic meaning they come in pairs of two for (as the prefix 'di' suggests) for example O2, and this is their original form as they do not have a full outer shell by nature and therefore form covalent bonds with another atom of themselves to get to one - oxygen is in group 6 meaning 6 outer shell electrons which makes sense as they would form one covalent bond meaning they share a pair of electrons, this in turn gives them 8. However other elements may not be di-atomic by nature so you are changing their properties by multiplying them by 2. You can however use the multiple in front to determine how many moles you have of each substance for instance if you have the equation 2Fe + 3O you would have a molar ratio of 2:3 you can use this to later discover the limiting reactant, so the one that is consumed first in the reaction, and limits the reaction when it is consumed. Once again hope this helped! sorry it is so long and late!!
What do you mean? If you go to any periodic table of elements you can find that oxygen ( "O" in group 7) has an atomic mass of 16 and sodium ("Na" in group 1) has an atomic mass of 23!
Really helpful. Couldn't understand moles at all but now I can happily battle through them. Great light hearted video and love the layout too.
THANK YOU SO MUCH LIKE YOU'VE SAVED MY LIFE FOR TOMORROW
omgg same
@TempoRyZe same.😂😭
Well same , after 4 years
Well same after 5 years
Why haven’t I discovered this video sooner! God bless youuuuu I literally understood everything 😂
I FINALLY UNDERSTAND!!!
THANK YOU!!!
oh my gosh where has this been my whole life?!
Revision=done for my chemistry GcSE tommorow- never understood this In class thank you ❤️❤️
how did it gooo
I wish you were my teacher!
got my gcse chem mock tomorrow, this explained it better in 12 minutes than many hours of lessons dedicated to moles. thanks!
Surprised this only has 10k views, very helpful

Best science videos ever !
Free science lessons has nothing on this
Got the exam tomorrow., thank you !!
After being taught for years and not understanding one 12min video has got me sorted. Life saver for my exam!!!
OMG thanx u saved my life for my chemistry test tomorrow. 😊😊😊

Better Than CZcamsr primrose kitten by far
High praise! 😊
this video made this topic so much easier to understand!!
This video is amazing! Now I feel much more confident going into my test tomorrow!!! Would reccomend to anyone struggling with moles and mass etc!
Thank you so much, this was so helpful for my revision. I will definitely remember the formula for moles because of the grams rams thing.
Im doing my double award chemistry gcse tomorrow and Im absolutely sh*tting myself and Im so thankful for your videos!

Thank you sooo much🙏❤️
Thank you sooooo much for this video. A real LIFE SAVER.. sending love 💕💕
Thank you!!!! you are so much better than my teacher!
Very helpful, sir! And your accent is awesome!👍😄
thankyou reall
y helped with my understanding of this i watched other videos but they were really complicated :)
Thanks for a clear explanation. Finally I get this
THANK YOUUU MY TEACHER TAUGHT IT TOO FAST AND I GOT CONFUSED WATCHING THIS MADE IT CLEARER
i have my chemistry gcse in 2 hours and your videos have helped me so much the last few days, thank you so much
THANK YOU SOOOO MUCH explained it so so so well!!
Thank you so much for helping me out
Thank you so much, I have a mock tomorrow and this has really helped me out!
This was great thank you sooo much!
Truly YOU are the besttttttttt❤❤❤❤❤
Wowwww better than my teacher
Can you cover igcse grade 9 chemistry
Thank you.... really bad at doing moles before
Very helpful!!!!!!!!!!!!!!
this is hard bur you expladed it well
yh he "expladed" it rllly well

Thank Jeebus someone can explain it in English. My chemistry teacher has been off for 4 months and supply teachers aren't very good at teaching.
Thanks! I understand it now, actually feels easy aswell now!
Thanks a lot for this,got a test tomorrow and I forgot how to do quantitative chemistry
your videos are so helpful❤️
3:18 I thought relative formula mass was for ionic compounds?
i was really thankful for ths vid thanks ! :)

This really helped, thank you so much
im so glad i found your youtube channel because you have helped me out so much!!! thank you!!
really good video, helped me understand moles and the whole idea pretty clearly
Helped me a lot. Thanks!!!
thank you man i didn’t understand this
Thank you so much this was so helpful!!!
Thanks
You are simply amazing!!!
Please can you do
Titration calc
Neutralisation calc
Gases and solutions calc
Atom economy % yield
Definitely!
Yes please real quick no time
New subscribers honestly I didn’t understand it and I hv Test Tomo but now I do thanks so much 💞🎉
All the best for it!

I think you need to balance the equation yourself, in some situations they won’t give it to you balanced.
@@noelle4145 thank you
I know
i think you rounded moles of iron (iii) oxide form 1.875 to 1.88 and that changed the result because i didn't and in the end i got 210 tonnes not 211
there will be a range
My exam i tmmrw and u hv saved me
i love this BUT HE WROTE IN BLACK SHARPIE ON A WHITEBOARD??? THAT DOESNT RUB OFF apart from that very helpful
It's paper, dude.
You are a Great teacher
Thank you, thank you ever so much
Thanks you for this!!

life savior ong
I learnt more from this than my actual chemistry lessons in school
bro ur the best
GRAMS OVER RAMS!!!!!!!!!!!!!!!!!!!!!
more examples of moles at the end plz
but seriously,thank you
Thanks❤️
Hello, can you explain the non-directional of ionic bonds and directional of covalent bonds please? I don't understand this logic, thanks a lot!
very clarifying
this tutorial ate 👁

hey, can you plsssss make a video on stoichiometry as soon as you can since my exams are near and i dont know anything
Stoichiometry is just the ratio of one reactant/product to another 😊
@@ScienceShorts oohhh. Thanks
I thought 2Fe and Fe2 both mean that there are 2 atoms of iron present? If so, your ‘ratio’ step wasn’t necessary.
thanks man
10:58 , we had ( Fe2 ) in the reactant then, we had ( 2Fe ) in the product, doesn't that make a difference? { I didn't even know what computational chemistry was, this is my introduction to it. So, forgive me if this is a silly question... )

do u already know the reason?i want to know too :(
@@danielmuzani7466 late reply but its because the question does not involve carbon in it so its pointless

at 3:39, why did you do oxygen twice? isn't it diatomic or is that not related to it?
Just a small query, for the last bit when we calculate the mass of Iron using the mole ratio, would the RAM not be 112 instead of 56 because on the formula it says “2Fe” so would you not multiply 56 by 2?
sorry this is so late BUT noooo! as basically you would only multiply by 2 if it is the subscript (e.g Fe2) hope that helps :) the reasoning is that some elements are di-atomic meaning they come in pairs of two for (as the prefix 'di' suggests) for example O2, and this is their original form as they do not have a full outer shell by nature and therefore form covalent bonds with another atom of themselves to get to one - oxygen is in group 6 meaning 6 outer shell electrons which makes sense as they would form one covalent bond meaning they share a pair of electrons, this in turn gives them 8.

Once again hope this helped! sorry it is so long and late!!
1:15 Why did you use a dot for the first multiplication but an X for the second? Shouldn't it always be a dot in chemistry and physics?
its a decimal place, dots are never used as a multiplication symbol in the UK
