Question

Calculate molecular mass of NH4OH ( At. Mass. N=14u, H=1u, O​

Answer 1

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

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
