1.2.6 Determine molecular formula given empirical formula & experimental data IB Chemistry SL

1.2.6 Determine the molecular formula when given both the empirical formula and experimental data. The molecular formula eg XXAXXAXXA is made up of one or more of the empirical formula, XXA, in this case.Eg A molecule Y has a molar mass of 39g/mol and an empirical formula of CH. What is molecule Y?CH = (12+1) g/mol 39/13 = 3 SOMolecular formula is 3 times the empirical formula = 3x CH = C3H3
