Molar and molecular weight of AsI3

• Relative molecular weight of AsI3: 455.63501
• Molar mass of AsI3: 455.63501 g/mol (0.45564 kg/mol)

Calculation of the relative molecular and molar mass of AsI3

• Mr[AsI3] = Ar[As] + Ar[I] * 3 = 74.9216 + 126.90447 * 3 = 455.63501
• Molar mass (kg/mol) = Mr[AsI3] : 1000 = 455.63501 : 1000 = 0.45564 kg/mol

AsI3: percent composition by element
