Molar and molecular weight of NaBr

• Molecular formula: NaBr or BrNa
• Relative molecular weight of NaBr: 102.89376928
• Molar mass of NaBr: 102.89376928 g/mol (0.10289 kg/mol)

Calculation of the relative molecular and molar mass of NaBr

• Mr[NaBr] = Ar[Br] + Ar[Na] = 79.904 + 22.98976928 = 102.89376928
• Molar mass (kg/mol) = Mr[NaBr] : 1000 = 102.89376928 : 1000 = 0.10289 kg/mol

NaBr: percent composition by element

• Bromine (Br) = 79.904 : 102.89376928 * 100 = 77.657 %
• Sodium (Na) = 22.98976928 : 102.89376928 * 100 = 22.343 %
