The molecular formula of  Compound shows the actual number of atoms of different elements contained in one molecule of the compound.
   Eg:the molecular formula of glucose is C   H      O
                                                              6    12    6

Molecular mass : a chemical formula that indicates the kinds of atoms and the                            number of each kind in a molecule of a compound.
For example:
The molecular mass of carbon dioxide -
                                    The elements present are carb
on and oxygen.One atom of carbon and 2 atoms of oxygen are present in a molecule of carbon dioxide.Hence the formula of carbon dioxide is CO2 (2 is sub script).
