Molar and molecular weight of Br2Cu

• Molecular formula: Br2Cu or CuBr2
• Relative molecular weight of Br2Cu: 223.354
• Molar mass of Br2Cu: 223.354 g/mol (0.22335 kg/mol)

Calculation of the relative molecular and molar mass of Br2Cu

• Mr[Br2Cu] = Ar[Br] * 2 + Ar[Cu] = 79.904 * 2 + 63.546 = 223.354
• Molar mass (kg/mol) = Mr[Br2Cu] : 1000 = 223.354 : 1000 = 0.22335 kg/mol

Br2Cu: percent composition by element

• Bromine (Br) = 159.808 : 223.354 * 100 = 71.549 %
• Copper (Cu) = 63.546 : 223.354 * 100 = 28.451 %
