Molar and molecular weight of N2O3

• Relative molecular weight of N2O3: 76.0116
• Molar mass of N2O3: 76.0116 g/mol (0.07601 kg/mol)

Calculation of the relative molecular and molar mass of N2O3

• Mr[N2O3] = Ar[N] * 2 + Ar[O] * 3 = 14.0067 * 2 + 15.9994 * 3 = 76.0116
• Molar mass (kg/mol) = Mr[N2O3] : 1000 = 76.0116 : 1000 = 0.07601 kg/mol

N2O3: percent composition by element

• Nitrogen (N) = 28.0134 : 76.0116 * 100 = 36.854 %
• Oxygen (O) = 47.9982 : 76.0116 * 100 = 63.146 %
