        The aforementioned steps gives you the simplest ratio
        
        From the empirical formula, you can work out the molecular formula if you know the relative formula mass (Mr) of the compound.
        
        For example: For example, the empirical formula of a hydrocarbon is CH2 and its Mr is 42.
        
        Since, the mass of the atoms in the empirical formula is 14. So, 42: 14 = 3
        
        You need to multiply the numbers in the empirical formula by 3
        
        The molecular formula of the hydrocarbon is therefore C3H6.
