Calculate The Molar Mass of The Following Substances Nh3

Reviewed by Calculator Editorial Team

Calculating the molar mass of ammonia (NH3) is a fundamental chemistry calculation that helps determine the mass of one mole of the compound. This guide explains the process step-by-step, provides a calculator for quick results, and includes practical examples.

How to Calculate Molar Mass

The molar mass of a compound is calculated by summing the atomic masses of all atoms in its chemical formula. For ammonia (NH3), you need the atomic masses of nitrogen (N) and hydrogen (H).

Key Concept

Molar mass is expressed in grams per mole (g/mol) and is essential for stoichiometric calculations in chemistry.

Steps to Calculate Molar Mass

  1. Identify the chemical formula of the substance (NH3 for ammonia).
  2. Count the number of each type of atom in the formula.
  3. Find the atomic mass of each element from the periodic table.
  4. Multiply each atomic mass by the number of atoms of that type in the formula.
  5. Sum all the values to get the molar mass.

Molar Mass Formula

Formula

Molar Mass = (Number of N atoms × Atomic Mass of N) + (Number of H atoms × Atomic Mass of H)

The atomic masses used are:

  • Nitrogen (N): 14.007 g/mol
  • Hydrogen (H): 1.008 g/mol

Worked Example

Let's calculate the molar mass of ammonia (NH3):

  1. Count the atoms: 1 N and 3 H.
  2. Multiply: (1 × 14.007) + (3 × 1.008) = 14.007 + 3.024 = 17.031 g/mol.

The molar mass of NH3 is 17.031 g/mol.
