Calculate the molar mass of Nitric acid (HNO3). 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. The smallest unit of a compound is molar mass, which is one-twelfth of the mass of one carbon atom – 12 atoms.

• The notion of molar mass can be used to calculate how many grams of substance are necessary when we know the number of moles required.
• The molar mass, also known as molecular weight, is the sum of all the atoms that make up a mole of a molecule’s total mass in grams. The unit of measurement is grams per mole.

Given

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.
