MOLECULAR FORMULAS To determine the molecular formula for a compound: 1) The molecular weight is always a multiple of the empirical formula weight (i.e., M.W. = n × E.F.W.) To determine n, divide the given molecular weight by the empirical formula weight.For every hydrogen, there's a carbon. The way to go back, you can go from the molecular formula to the empirical formula very easily. You just find the greatest common divisor of the number of atoms in the molecule. So, the greatest common divisor of six and six is obviously six, so you divide both of these by six and you get the empirical formula.
