Molar and molecular weight of AlI3

• Relative molecular weight of AlI3: 407.6949486
• Molar mass of AlI3: 407.6949486 g/mol (0.40769 kg/mol)

Calculation of the relative molecular and molar mass of AlI3

• Mr[AlI3] = Ar[Al] + Ar[I] * 3 = 26.9815386 + 126.90447 * 3 = 407.6949486
• Molar mass (kg/mol) = Mr[AlI3] : 1000 = 407.6949486 : 1000 = 0.40769 kg/mol

AlI3: percent composition by element

• Aluminum (Al) = 26.9815386 : 407.6949486 * 100 = 6.618 %
