An empirical formula gives the simplest and most reduced whole number ratio of atoms whereas a molecular formula gives the actual ratio of atoms in a compound.


For example, the molecular formula of glucose is #C_6H_12O_6#, and the empirical formula of glucose is #CH_2O#.

As you can see, the empirical formula is the simplified ratio of the molecular formula whereas the molecular formula isn't simplified at all.
