Molar and molecular weight of HgBr2

• Relative molecular weight of HgBr2: 360.398
• Molar mass of HgBr2: 360.398 g/mol (0.3604 kg/mol)

Calculation of the relative molecular and molar mass of HgBr2

• Mr[HgBr2] = Ar[Hg] + Ar[Br] * 2 = 200.59 + 79.904 * 2 = 360.398
• Molar mass (kg/mol) = Mr[HgBr2] : 1000 = 360.398 : 1000 = 0.3604 kg/mol

HgBr2: percent composition by element

• Mercury (Hg) = 200.59 : 360.398 * 100 = 55.658 %
• Bromine (Br) = 159.808 : 360.398 * 100 = 44.342 %
