Molar and molecular weight of N2O4

• Relative molecular weight of N2O4: 92.011
• Molar mass of N2O4: 92.011 g/mol (0.09201 kg/mol)

Calculation of the relative molecular and molar mass of N2O4

• Mr[N2O4] = Ar[N] * 2 + Ar[O] * 4 = 14.0067 * 2 + 15.9994 * 4 = 92.011
• Molar mass (kg/mol) = Mr[N2O4] : 1000 = 92.011 : 1000 = 0.09201 kg/mol

N2O4: percent composition by element

• Nitrogen (N) = 28.0134 : 92.011 * 100 = 30.446 %
• Oxygen (O) = 63.9976 : 92.011 * 100 = 69.554 %
