Relationship between Molecular formula and Empirical formula

                 Relationships between   Molecular Formula and Empirical formula as follow

Molecular Formula = n x Empirical formula

n = Molecular Formula/ Empirical formula

The   molecule  of  benzene  having  molecular  mass  as 78 µ.

Hence n = n= Molecular Formula  / Empirical formula 

                      

                    =78µ/(12+1)µ

                     

                    =78/13

                      

                   =6

Molecular formula of benzene is 6 x (CH ) =C₆H₆

Molecular Formula	Empirical formula
C2H6	CH3
C2H4	CH2
B2H6	BH3
