Molar and molecular weight of GaBr3

• Relative molecular weight of GaBr3: 309.435
• Molar mass of GaBr3: 309.435 g/mol (0.30944 kg/mol)

Calculation of the relative molecular and molar mass of GaBr3

• Mr[GaBr3] = Ar[Ga] + Ar[Br] * 3 = 69.723 + 79.904 * 3 = 309.435
• Molar mass (kg/mol) = Mr[GaBr3] : 1000 = 309.435 : 1000 = 0.30944 kg/mol
