Am I correct in saying that since a mole of Na for example is 23 grams, so 4 moles of Na would just be 4 x 23 = 92 grams. and 0.4 moles of Na would be 9.2 grams. If I had

If I had 2 moles of C2H3O2 (acetate) it would be the formula weight x 2?

carbon 2 x 12 = 24 hydrogen 3 x 1= 3 and 0xygen is 2 x 16 =32 24+3+32= 59

2 x 59 = 118 grams would be 2 moles of acetate

0.50 (1/2) moles is 59 grams

am I correct????

thanks

Chemistry moles question. How many moles in a substance or compound?

yes, finding the mass of x moles in a compound = x(mass). If you want to find out the number of atoms in the compound, it is x(6.022*10^23) where x= the number of moles.

Reply:yes, you are correct

Reply:yes you are correct. the atomic weight is the weighted average of all its isotopes, but it is also the mass of one mole of that atom.
