Suppose that the formula of the elements is the empirical formula where the elements are more simple whole number ratioThe empirical mass = 2 X atomic mass of carbon + 5 X atomic mass of hydrogen + mass of The empirical mass = 2 X 12 + 5 + 16 = 45 The ratio of the molecular mass and the empirical mass = 90 / 45 = 2 Molecular formula is obtained by multiplying the empirical formula with this relationship / factormolecular formula = 2 X (C2H5O) = C4H10O2
