Molar and molecular weight of NaNO2

• Molecular formula: NaNO2 or NNaO2
• Relative molecular weight of NaNO2: 68.99526928
• Molar mass of NaNO2: 68.99526928 g/mol (0.069 kg/mol)

Calculation of the relative molecular and molar mass of NaNO2

• Mr[NaNO2] = Ar[N] + Ar[Na] + Ar[O] * 2 = 14.0067 + 22.98976928 + 15.9994 * 2 = 68.99526928
• Molar mass (kg/mol) = Mr[NaNO2] : 1000 = 68.99526928 : 1000 = 0.069 kg/mol

NaNO2: percent composition by element

• Nitrogen (N) = 14.0067 : 68.99526928 * 100 = 20.301 %
• Sodium (Na) = 22.98976928 : 68.99526928 * 100 = 33.321 %
• Oxygen (O) = 31.9988 : 68.99526928 * 100 = 46.378 %
