Molar and molecular weight of AsBr3

• Relative molecular weight of AsBr3: 314.6336
• Molar mass of AsBr3: 314.6336 g/mol (0.31463 kg/mol)

Calculation of the relative molecular and molar mass of AsBr3

• Mr[AsBr3] = Ar[As] + Ar[Br] * 3 = 74.9216 + 79.904 * 3 = 314.6336
• Molar mass (kg/mol) = Mr[AsBr3] : 1000 = 314.6336 : 1000 = 0.31463 kg/mol
