Molar and molecular weight of AlN

• Relative molecular weight of AlN: 40.9882386
• Molar mass of AlN: 40.9882386 g/mol (0.04099 kg/mol)

Calculation of the relative molecular and molar mass of AlN

• Mr[AlN] = Ar[Al] + Ar[N] = 26.9815386 + 14.0067 = 40.9882386
• Molar mass (kg/mol) = Mr[AlN] : 1000 = 40.9882386 : 1000 = 0.04099 kg/mol

AlN: percent composition by element

• Aluminum (Al) = 26.9815386 : 40.9882386 * 100 = 65.828 %
• Nitrogen (N) = 14.0067 : 40.9882386 * 100 = 34.172 %
