no one want to help me out :/? I remember here used to have a few chemist always posting and solving people's question.. *pump*

sorry man but I don't understand your explanation. I don't think my answer is the mole of H instead of the number of atoms. If you read it carefully, what I did is divided the given molar mass by C_1H_1's molar mass. because (CH)n <- the n is what I was looking for. so, I don't know. would be...

I need help for these questions... I do it tho, but some of them are wrong :/ 1) The empirical formula of styrene is CH; the molar mass of styrene is 104.14 g/mol. What number of H atoms present in a 4.50g sample of styrene? my answer is 8 because the ratio between C and H in styrene is...
