Molar and molecular weight of N2O

• Relative molecular weight of N2O: 44.0128
• Molar mass of N2O: 44.0128 g/mol (0.04401 kg/mol)

Calculation of the relative molecular and molar mass of N2O

• Mr[N2O] = Ar[N] * 2 + Ar[O] = 14.0067 * 2 + 15.9994 = 44.0128
• Molar mass (kg/mol) = Mr[N2O] : 1000 = 44.0128 : 1000 = 0.04401 kg/mol

N2O: percent composition by element

• Nitrogen (N) = 28.0134 : 44.0128 * 100 = 63.648 %
• Oxygen (O) = 15.9994 : 44.0128 * 100 = 36.352 %
