Molar and molecular weight of N2

• Relative molecular weight of N2: 28.0134
• Molar mass of N2: 28.0134 g/mol (0.02801 kg/mol)

Calculation of the relative molecular and molar mass of N2

• Mr[N2] = Ar[N] * 2 = 14.0067 * 2 = 28.0134
• Molar mass (kg/mol) = Mr[N2] : 1000 = 28.0134 : 1000 = 0.02801 kg/mol
