Question

Calculate the molecular mass of nitric acid? (HNO3) with explanation​

Answer 1

Answer:

Atomic mass of H=1U, N=14u, O=16u. Answer: The molar mass of the chemical substance is equal to the sum of the atomic mass of the individual atoms. (1 × 1) +(1 × 14) + (16×3) = 63 u.

Answer 2

Answer:

The molar mass of the chemical substance is equal to the sum of the atomic mass of the individual atoms. (1 × 1) +(1 × 14) + (16×3) = 63 u.

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.
