You may have noticed that % composition vs Melting Point graphs are given in % Mole not 96 Weight. This is because melting point depression is a colligative property (review in your general chemistry text) that depends on the moles of impurity, the same number of moles of impurity of two different compounds will cause the same melting point depression! Before the advent of mass spectrometry this was one of the techniques used to determine the molecular weight of compounds....
