Wow
11yrs ago and here i am watching. It's my advance study lesson my 1st teacher in pharmacy😆
me too
Thanks
Great video but sound is too low
Thank you
You are welcome!
جاي نتابعك من العراق وكلشي ماافتهم وباجر فاينل
عاشت ايدك دكتور خوش تشرح ❤
This is fantastic; I appreciate the actual explanation of the technique being used (e.g. dimensional analysis) instead of just steam rolling through the problem.
❤
Thanks for making these

Sir last part cant understand sir also sir meq is said for single ion ..i.e example we cant say meq of kcl is 100 but we xan say meq of k is 100 i.e meq cant be found for molecule but only for single ion ..
These videos...... ❤❤ Just soo helpful, and we're extremely grateful 🙏
What does the sensitivity requirement mean in the questions?
I’m Late !!!! But Thank You !!!! Your an awesome teacher !!!!
Thank you professor 🤍
Mr.wojcik ik you might not respond as I see it’s been a long time, can you make a video ho to get mg to hrs let’s say a doctor says you have to take two a day or 1 a day how do you solve to get those doses
Thank you
Thanks sir. Im in pharm tech school and while many of these make complete sense to me I struggled with drip rates. appreciate these videos!
I wish I could take your class cuz this is so confusing. I have no help in southern Oklahoma. No one teaches this. I'm all alone online and it ain't working
Ok how about how much silver nitrate ( in grams) must be used in preparing 600mL of a solution such that 20 mL diluted to 1L will yield a 1:5000 solution.
A physician prescribed an antibiotic to be mixed in white petrolatum to produce a 25% antibiotic preparation. The physician later changed the protocol to be only 12.5%. How much white petrolatum must be mixed with each 6 oz ointment container of 25% preparation to make the new 12.5% preparation? Calculate your answer in grams. This is a work book question but really doesnt make since. Can you help
Well, since 12.5% is half of 25%, you would add 6 oz of white petrolatum. If you are using 30 g per ounce it would be 180 g.
@@BradWojcikPharmD , ok I understand that but where did you come up with the 30. Can you write it with formula
Please email me at brad.wojcik@gmail.com so I can show you how it is done.
@@BradWojcikPharmD , I did email you I hope you received it
@@pammidkiff1893 HI Pam. No I didn't get it. Can you try again. Brad.wojcik@gmail.com
This is sooo helpful thank you thank you!
This video just kept me from a panic attack from my studies! Lol Thanks for showing what my course video didn’t!
good
smart
Thank you so much.Doctor Brad for this useful video ❤️❤️
Hi Mr.Brad. Could you please help with this problem? What volume of a 1 in 400 v/v solution is needed to produce 5L of a 1 in 2000 v/v solution? I am not able to do that from the first method?
You can do it a couple of ways. First calculate number of grams in 5 L of the 1:2000 solution then calculate the volume of the 1:400 solution needed to get those grams. 5 L(1 g/2000 mL) (1000 mL/L) =2.5 g. 2.5 g (400 mL/1 g) =1000 mL. You can also use V1 C1 = V2 C2.
What an amazing find! Why is everything else taught so complicated?! Thank you so much. I've just downloaded your book too! Thanks again 😃
I just downloaded this your 📚 📕 book. It was free………. Woowwwww you’re beautiful person. Ty Bodisatva you came back for us.woowwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
How do you know which way to place the ratios im confused and getting them wrong because of that
If you need to cancel units, you put the ratios in so that the units are opposite of what is in place. For example, if mg are on top and you need to cancel them, then the mg in the ratio would be on the bottom.
Do you only look at the given and that will tell you the next steps to make
@@bryannpowell4953 You can start with the given and the units of the answer. That way you can work from either end.
Now im having a problem with the extra information in the problem and just knowing what the problem is asking me and including the right ratio
Like this problem the np has ordered 100 mg IM bid of a drug which is available in 5 ml vials labeled 80mg/ml. How many ml will be administered per dose?
Thank you for turning an hour lecture to 10 mins boss man🙏🏾
Thank you! The textbook we were assigned did a very bad explaining this concept so I had to look it up. I'm glad I ran into your video first
Thank you!
still having trouble with powder volumes there confusing
And 400
How u got 600
You multiply (30/50) x 1000 mL
@@BradWojcikPharmD yeah I figure it out, I was doing times 100 and got 60, thank you so much this is the best explanation ever
This was helpful
Thank you so much, this helps a lot. :)
Thank you for thus video Dr. Brad. This is a big help!

Its hard to see the conversion factors written in the lighter color.
PharmaD are you retired?If not how come you're not doing recent math calculations for pharmacy technician 2021?
Thank you!
Thank you, Dr. Brad. I hope you post more videos. I'm a foreign nurse I. These videos help me understand the concepts in the US.
I want to order your book for my students and I am having a hard time locating the contact info for your publisher. Can you help?
It is on Amazon. You can email me at brad.wojcik@gmail.com for more information.

A 10-milliliter graduate weighs 42.745 grams. When 5 milliliters of distilled water are measured in it, the com- bined weight of graduate and water is 47.675 grams. By definition, 5 milliliters of water should weigh 5 grams. Cal- culate the weight of the measured water and express any deviation from 5 grams as percentage of error
