Molar and molecular weight of Hg2Br2

• Relative molecular weight of Hg2Br2: 560.988
• Molar mass of Hg2Br2: 560.988 g/mol (0.56099 kg/mol)

Calculation of the relative molecular and molar mass of Hg2Br2

• Mr[Hg2Br2] = Ar[Hg] * 2 + Ar[Br] * 2 = 200.59 * 2 + 79.904 * 2 = 560.988
• Molar mass (kg/mol) = Mr[Hg2Br2] : 1000 = 560.988 : 1000 = 0.56099 kg/mol
