Thanks for posting this video, it was very helpful.
I was struggling a lot in chemistry class. Thanks for breaking it down for
me 🙂 having a test tomorrow.
chem calculations.
You’re very welcome, Yui! Glad you found my site and I hope you’ll keep
checking back throughout the semester. Tell a friend!
In the first example, shouldn’t the answer be 98,5g?
(3,05*10ˇ25/6,022*10ˇ23)*197
thankss….you’re a great tutor…..you made it easy for me
When calculating the 2nd example what mode should my calculator be in? (I
have a sharp EL-531X calculator if that helps)
im confused how did you get the resulting exponents in the answer, for
example 10^-3
please help
thank you I like it
very very interesting, thank you very much.
I’m trying to determine how many moles of Ca^+2 can be found in 3.5 moles
of Ca¬3(PO¬4)¬2 [¬ represents subscript]
Also, how many hydroxide ions are in 2 moles of Fe(OH)¬2
Do you have a video that goes more into detail about those two things?
I’m trying to follow your examples, but none of them are seeming to get me
to the right answer for these particular problems.
Thank you. Your videos have been very helpful to me!!!
You are the best!
You my friend….are very awesome !!!
very helpful, thankyou!
So, isn’t every equation has 1 moles and it is equal to the Avogadro’s
number?
I can’t thank you enough for your fabulous and well explained videos! I’m
starting to enjoy Chemistry just a little more thanks to you 🙂
Thanks so much!!!!!!It helps me much!!!!!My chemistry teacher at school
always teach in a hurry and dosent make sure whenther the student is
understand or not lol…
you have saved me.
How did you get 9976.06g in the first answer? I did
196.97 * 6.022EE23 and got = 1.186 15334 26
unfortunately i came here after failing my test. nevertheless, thanks man
Im sorry but i have no idea what your doing…
For example with the molar mass and Avogadro’s #.
What are you multiplying?
You’re my hero! God bless you Doctor.
Omg this was so helpful, ty so much. I am going to show this to my whole
chem class so people will actually know what is going on
Thanks! I forgot how to do this, hehe.
This was really helpful, I was just wondering what you multiplied to get
9976.06g in the first example?
