What is the molecular formula of a compound with an empirical formula of CH and a molecular mass of 78?
Molecular weight = n $\times$ empirical weight, n represents the no. of atoms. ->So, molecular formula = (CH)$_n$ = (CH)$_6$ =C$_6$H$_6$; in this case we substituted the calculated value of n. ->Therefore, the molecular formula of the compound having the molecular weight 78 g/mol is (D) – C$_6$H$_6$.

How do you find molecular weight from molecular formula?
Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
