For this question, we're told that the empirical formula for styrene is equal to ch.
00:14
Therefore, the empirical mass is equal to carbon plus hydrogen, which is 13 .0 grams per mole.
00:24
The question gives us the molar mass.
00:27
So this ratio here, n, i'm going to call it, is going to be molar mass divided by empirical mass.
00:34
The molar mass is 104 .14 grams per mole.
00:39
Empirical mass is 13 .0 grams per mole.
00:44
And dividing, we will get 8.
00:49
Therefore, the molecular formula is equal to 8 times the empirical formula.
00:59
So the formula for styrene would be c8h8...
