WebThe empirical formula mass = (2 x 12) + 5 = 29. Dividing 58 by 29 gives 2. So the molecular formula is 2 x the empirical formula = C4H10 (ii) Suppose a molecule has an empirical formula of simply CH, but a molecular mass of 78 (C = 12, H = 1). The empirical formula mass is 12 + 1 = 13. Therefore 78/13 = 6, so the molecular formula is 6 x CH = C6H6
