How many moles of molecules are there in 250 grams of hydrogen nitrate?
Answered by drwls
hydrogen nitrate is nitric acid, HNO3. The molecular weight (also called the molar mass) is 1 + 14 + (3x16) = 63 g per mole. (63.016 if you want to be more exact.) You have to look up the atomic weights of the atoms to get the "exact" value. H, N and O all have close to integer values for atomic weight.

250 g is 250/63 = ___ moles
