Molar and molecular weight of NaNO3

• Molecular formula: NaNO3 or NNaO3
• Relative molecular weight of NaNO3: 84.99466928
• Molar mass of NaNO3: 84.99466928 g/mol (0.08499 kg/mol)

Calculation of the relative molecular and molar mass of NaNO3

• Mr[NaNO3] = Ar[N] + Ar[Na] + Ar[O] * 3 = 14.0067 + 22.98976928 + 15.9994 * 3 = 84.99466928
• Molar mass (kg/mol) = Mr[NaNO3] : 1000 = 84.99466928 : 1000 = 0.08499 kg/mol

NaNO3: percent composition by element

• Nitrogen (N) = 14.0067 : 84.99466928 * 100 = 16.48 %
• Sodium (Na) = 22.98976928 : 84.99466928 * 100 = 27.048 %
• Oxygen (O) = 47.9982 : 84.99466928 * 100 = 56.472 %
