Answer

Molecular formula = C4H8O2 Molecular Formula - C8H8

Work Step by Step

2(12.0107 g/mol) + 4(1.0079 g/mol) + 15.9994 g/mol = 44.0524 g/mol Compute the molar mass of the empirical formula. A molecular formula is always a whole number multiple of the empirical formula. Divide the molecular molar mass by the empirical molar mass to get this whole number. 12.0107 g/mol + 1.0079 g/mol = 13.0186 g/mol Compute the molar mass of the empirical formula. A molecular formula is always a whole number multiple of the empirical formula. Divide the molecular molar mass by the empirical molar mass to get this whole number.
