Question

calculate the molar mass of nitric acid and HNO3 and calcium carbonatecalculate the molar mass of nitric acid HNO3 and calcium carbonate

Answer 1

Answer:

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.

Explanation:

Answer 2

Answer:

Explanation:

H= 1u

O= 16u

N=14u

(1×1)+(14×1)+(16×3)

1+14+48
