how many moles of carbon are in 3 moles of C8H10N4O2?

Question

I dont want the answer but rather how to find out the answer so i can do it on my own.....

Answer 1

There are 8 carbon atoms in each molecule of C8H10N4O2. If you have 3 moles of this molecule you will have 3 x 8 = 24 moles of carbon atoms.

Answer 2

24.

A mole is a quantity of molecules. So you have 3 moles of C8H10N4O2. Each molecule with 8 Carbons. Multiply.

Answer 3

8 Carbons in C8H10N4O2, so if there are 3 moles of C8H10N4O2 you of course multiply them together to get 24.

Answer 4

I believe from my days of knowing organic chemistry that there would be 8
drop your #'s below the letter so...C=carbon 8 is the amount of atoms. Then H=hydrogen, 10 is the amount of atoms, then N=nitrogen,that would be 4 atoms , and the last is oxygen , which has 2 atoms. I cant remember how many molecules are in a mole?

Answer 5

8 carbons per molecule, 3 moles of molecules...

8 * 3 = 24

Answer 6

Okay, everyone here has it wrong so far. THE ANSWER IS NOT 24!!!!

Find the formula weight of your molecule. Then set up a proportion of 3/(f.w. of molecule)=x(your variable)/12(f.w. of carbon)
Then cross multiply and solve for x.

Answer 7

There are 24

8x3=24

Answer 8

ok its like you have to add up all the molecular weights of all the atoms

then divide

then figure the percentage of carbon
