Dear studnet 
The "molar mass" of any substance indicates the addition of atomic masses of constituent atoms. In other words, the atomic mass must be added to get the "molar mass" of substance.
Hence, to calculate the molar mass, we must know the atomic masses of component atoms. Here, for the molar mass of nitric acid:
Atomic mass of H  =  1.001 u
Atomic mass of N = 14.01 u
Atomic mass of O  = 16.0 u
63.01 g/mol is the molecular mass of nitric acid

Dear student

Molecular mass of HNO3
 is the sum of the atomic masses of H,NO
So 1+14+16×3=63 u.
