Molar and molecular weight of CsBr

• Relative molecular weight of CsBr: 212.8094519
• Molar mass of CsBr: 212.8094519 g/mol (0.21281 kg/mol)

Calculation of the relative molecular and molar mass of CsBr

• Mr[CsBr] = Ar[Cs] + Ar[Br] = 132.9054519 + 79.904 = 212.8094519
• Molar mass (kg/mol) = Mr[CsBr] : 1000 = 212.8094519 : 1000 = 0.21281 kg/mol

CsBr: percent composition by element

• Cesium (Cs) = 132.9054519 : 212.8094519 * 100 = 62.453 %
• Bromine (Br) = 79.904 : 212.8094519 * 100 = 37.547 %
