How many Fe atoms and how many moles of Fe atoms are in 250.0 g of iron?
and
The empirical formula of styrene is CH; the molar mass of styrene is 104.14 g/mol. How many H atoms are present in a 1.10 g sample of styrene?
I did most of the work for both problems but i can't seem to get the last parts. Just so you guys don't think I'm trying to have others do my homework, i just generally don't understand these types of problems.
Thank you =D
