The molar mass of NH4NO3 (Ammonium Nitrate) is calculated by adding the atomic masses of all the atoms in the molecule. Here’s how it’s done:
- Nitrogen (N) has an atomic mass of 14.01 g/mol.
- Hydrogen (H) has an atomic mass of 1.01 g/mol.
- Oxygen (O) has an atomic mass of 16.00 g/mol.
NH4NO3 consists of:
- 2 Nitrogen atoms: 2 × 14.01 = 28.02 g/mol
- 4 Hydrogen atoms: 4 × 1.01 = 4.04 g/mol
- 3 Oxygen atoms: 3 × 16.00 = 48.00 g/mol
Adding these together gives the molar mass of NH4NO3:
28.02 + 4.04 + 48.00 = 80.06 g/mol
Therefore, the molar mass of NH4NO3 is 80.06 g/mol.
