Molar and molecular weight of CeBr3

• Relative molecular weight of CeBr3: 379.828
• Molar mass of CeBr3: 379.828 g/mol (0.37983 kg/mol)

Calculation of the relative molecular and molar mass of CeBr3

• Mr[CeBr3] = Ar[Ce] + Ar[Br] * 3 = 140.116 + 79.904 * 3 = 379.828
• Molar mass (kg/mol) = Mr[CeBr3] : 1000 = 379.828 : 1000 = 0.37983 kg/mol
