Molar and molecular weight of N2O5

• Molecular formula: N2O5 or NO2NO3
• Relative molecular weight of N2O5: 108.0104
• Molar mass of N2O5: 108.0104 g/mol (0.10801 kg/mol)

Calculation of the relative molecular and molar mass of N2O5

• Mr[N2O5] = Ar[N] * 2 + Ar[O] * 5 = 14.0067 * 2 + 15.9994 * 5 = 108.0104
• Molar mass (kg/mol) = Mr[N2O5] : 1000 = 108.0104 : 1000 = 0.10801 kg/mol

N2O5: percent composition by element

• Nitrogen (N) = 28.0134 : 108.0104 * 100 = 25.936 %
• Oxygen (O) = 79.997 : 108.0104 * 100 = 74.064 %
