Molar and molecular weight of ZnBr2

• Molecular formula: ZnBr2 or Br2Zn
• Relative molecular weight of ZnBr2: 225.217
• Molar mass of ZnBr2: 225.217 g/mol (0.22522 kg/mol)

Calculation of the relative molecular and molar mass of ZnBr2

• Mr[ZnBr2] = Ar[Br] * 2 + Ar[Zn] = 79.904 * 2 + 65.409 = 225.217
• Molar mass (kg/mol) = Mr[ZnBr2] : 1000 = 225.217 : 1000 = 0.22522 kg/mol

ZnBr2: percent composition by element

• Bromine (Br) = 159.808 : 225.217 * 100 = 70.957 %
• Zinc (Zn) = 65.409 : 225.217 * 100 = 29.043 %
