Question

calculate the mularmass of electric acid HNO3

​

Answer 1

Explanation:

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

Given

Atomic mass of H = 1u

Atomic mass of N = 14 u

Atomic mass of O = 16u

The molar mass of HNO3 is

(1 × 1) +(1 × 14) + (16×3) = 63 u
