Molar and molecular weight of AgBr

• Relative molecular weight of AgBr: 187.7722
• Molar mass of AgBr: 187.7722 g/mol (0.18777 kg/mol)

Calculation of the relative molecular and molar mass of AgBr

• Mr[AgBr] = Ar[Ag] + Ar[Br] = 107.8682 + 79.904 = 187.7722
• Molar mass (kg/mol) = Mr[AgBr] : 1000 = 187.7722 : 1000 = 0.18777 kg/mol

AgBr: percent composition by element

• Silver (Ag) = 107.8682 : 187.7722 * 100 = 57.446 %
• Bromine (Br) = 79.904 : 187.7722 * 100 = 42.554 %
