Molar and molecular weight of MnBr2

• Molecular formula: MnBr2 or Br2Mn
• Relative molecular weight of MnBr2: 214.746045
• Molar mass of MnBr2: 214.746045 g/mol (0.21475 kg/mol)

Calculation of the relative molecular and molar mass of MnBr2

• Mr[MnBr2] = Ar[Br] * 2 + Ar[Mn] = 79.904 * 2 + 54.938045 = 214.746045
• Molar mass (kg/mol) = Mr[MnBr2] : 1000 = 214.746045 : 1000 = 0.21475 kg/mol
