Molar and molecular weight of Br2Mo

• Molecular formula: Br2Mo or MoBr2
• Relative molecular weight of Br2Mo: 255.748
• Molar mass of Br2Mo: 255.748 g/mol (0.25575 kg/mol)

Calculation of the relative molecular and molar mass of Br2Mo

• Mr[Br2Mo] = Ar[Br] * 2 + Ar[Mo] = 79.904 * 2 + 95.94 = 255.748
• Molar mass (kg/mol) = Mr[Br2Mo] : 1000 = 255.748 : 1000 = 0.25575 kg/mol

Br2Mo: percent composition by element

• Bromine (Br) = 159.808 : 255.748 * 100 = 62.487 %
• Molybdenum (Mo) = 95.94 : 255.748 * 100 = 37.513 %
