Molar and molecular weight of BiBr3

• Relative molecular weight of BiBr3: 448.6924
• Molar mass of BiBr3: 448.6924 g/mol (0.44869 kg/mol)

Calculation of the relative molecular and molar mass of BiBr3

• Mr[BiBr3] = Ar[Bi] + Ar[Br] * 3 = 208.9804 + 79.904 * 3 = 448.6924
• Molar mass (kg/mol) = Mr[BiBr3] : 1000 = 448.6924 : 1000 = 0.44869 kg/mol
