Molar and molecular weight of CaBr2

• Molecular formula: CaBr2 or Br2Ca
• Relative molecular weight of CaBr2: 199.886
• Molar mass of CaBr2: 199.886 g/mol (0.19989 kg/mol)

Calculation of the relative molecular and molar mass of CaBr2

• Mr[CaBr2] = Ar[Br] * 2 + Ar[Ca] = 79.904 * 2 + 40.078 = 199.886
• Molar mass (kg/mol) = Mr[CaBr2] : 1000 = 199.886 : 1000 = 0.19989 kg/mol

CaBr2: percent composition by element

• Bromine (Br) = 159.808 : 199.886 * 100 = 79.95 %
• Calcium (Ca) = 40.078 : 199.886 * 100 = 20.05 %
