Molar and molecular weight of BaCl2

• Relative molecular weight of BaCl2: 208.233
• Molar mass of BaCl2: 208.233 g/mol (0.20823 kg/mol)

Calculation of the relative molecular and molar mass of BaCl2

• Mr[BaCl2] = Ar[Ba] + Ar[Cl] * 2 = 137.327 + 35.453 * 2 = 208.233
• Molar mass (kg/mol) = Mr[BaCl2] : 1000 = 208.233 : 1000 = 0.20823 kg/mol

BaCl2: percent composition by element

• Barium (Ba) = 137.327 : 208.233 * 100 = 65.949 %
• Chlorine (Cl) = 70.906 : 208.233 * 100 = 34.051 %
