Molar and molecular weight of BaBr2

• Relative molecular weight of BaBr2: 297.135
• Molar mass of BaBr2: 297.135 g/mol (0.29714 kg/mol)

Calculation of the relative molecular and molar mass of BaBr2

• Mr[BaBr2] = Ar[Ba] + Ar[Br] * 2 = 137.327 + 79.904 * 2 = 297.135
• Molar mass (kg/mol) = Mr[BaBr2] : 1000 = 297.135 : 1000 = 0.29714 kg/mol
