the empirical formula for glucose is the simplest ratio of whole numbers components in the compound. While molecular formula is the actual composition of components in the compound. Empirical formula has been given. We need to find the mass of one empirical unit Mass of one empirical unit = CH₂O = (12 g/mol x1 + 1 g/mol x 2 + 16 g/mol x 1) = 30 g we need to find how many empirical units are there in the molecular formula mass of molecule - 180 g/mol how many empirical units in 1 molecule - 180 /30 = 6 therefore 6 empirical units = CH₂O x 6 molecular formula = C₆H₁₂O₆
