Computing Molar Mass of Sodium Nitrate Step by Step

Molar Mass of Sodium Nitrate: Step-by-Step Calculation

1. Identify Element Counts

Read NaNO3 and list how many atoms of each element are present:

  1. 1 atom of Sodium (Na)
  2. 1 atom of Nitrogen (N)
  3. 3 atoms of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Sodium (Na) ~= 22.990 g/mol
  2. Nitrogen (N) ~= 14.007 g/mol
  3. Oxygen (O) ~= 15.999 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Sodium (Na): 1 x 22.990 = 22.990 g/mol
  • Nitrogen (N): 1 x 14.007 = 14.010 g/mol
  • Oxygen (O): 3 x 15.999 = 48.000 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (1 x 22.990 + 1 x 14.007 + 3 x 15.999)

Molar Mass = 22.990 + 14.010 + 48.000

Molar Mass = 84.990 g/mol

Final rounded value shown on this page: 84.99 g/mol.
