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

C2H6
CH3
C2H4
CH2
B2H6
