Molar and molecular weight of Mg3N2

• Relative molecular weight of Mg3N2: 100.9284
• Molar mass of Mg3N2: 100.9284 g/mol (0.10093 kg/mol)

Calculation of the relative molecular and molar mass of Mg3N2

• Mr[Mg3N2] = Ar[Mg] * 3 + Ar[N] * 2 = 24.305 * 3 + 14.0067 * 2 = 100.9284
• Molar mass (kg/mol) = Mr[Mg3N2] : 1000 = 100.9284 : 1000 = 0.10093 kg/mol

Mg3N2: percent composition by element

• Magnesium (Mg) = 72.915 : 100.9284 * 100 = 72.244 %
• Nitrogen (N) = 28.0134 : 100.9284 * 100 = 27.756 %
