Molar and molecular weight of Al(NO3)3

• Relative molecular weight of Al(NO3)3: 212.9962386
• Molar mass of Al(NO3)3: 212.9962386 g/mol (0.213 kg/mol)

Calculation of the relative molecular and molar mass of Al(NO3)3

• Mr[Al(NO3)3] = Ar[Al] + Ar[N] * 3 + Ar[O] * 9 = 26.9815386 + 14.0067 * 3 + 15.9994 * 9 = 212.9962386
• Molar mass (kg/mol) = Mr[Al(NO3)3] : 1000 = 212.9962386 : 1000 = 0.213 kg/mol

Al(NO3)3: percent composition by element

• Aluminum (Al) = 26.9815386 : 212.9962386 * 100 = 12.668 %
