Molar and molecular weight of TaBr3

• Relative molecular weight of TaBr3: 420.6599
• Molar mass of TaBr3: 420.6599 g/mol (0.42066 kg/mol)

Calculation of the relative molecular and molar mass of TaBr3

• Mr[TaBr3] = Ar[Ta] + Ar[Br] * 3 = 180.9479 + 79.904 * 3 = 420.6599
• Molar mass (kg/mol) = Mr[TaBr3] : 1000 = 420.6599 : 1000 = 0.42066 kg/mol
