Answer:
C6H6
Explanation:
We divide each percentage by the relative atomic mass of the element:
Carbon: 92.31 / 12.011 = 7.68
Hydrogen: 7.69 / 1.008 = 7.63
So the ratio of carbon to hydrogen is 1:1.
Empirical formula is CH - which has a MM of 13.019
The RMM is 78 so the molecular formula = 78/13.019 = 6 * CH
So it is C6H6 (Benzene).
