The empirical formula of benzene is CH. Its molecular weight is given as 78.1 amu.
To find the molecular formula, we divide the molecular weight by the empirical formula weight:
Molecular weight = 78.1 amu
Empirical formula weight = 13.02 amu
78.1 amu / 13.02 amu = 6
Therefore, the molecular formula of benzene is C6H6.
The molecular formula is C6H6.
