Calculate the molar mass of Nitric acid (HNO3). Atomic mass of H=1U, N=14u, O=16u


The molar mass of the chemical substance is equal to the sum of the atomic mass of the individual atoms.


  1. Atomic mass of H = 1u
  2. Atomic mass of N = 14 u
  3. Atomic mass of O = 16u

The molar mass of HNO3 is

(1 × 1) +(1 × 14) + (16×3) = 63 u.
