Molar and molecular weight of Mg(ClO4)2

• Molecular formula: Mg(ClO4)2 or Cl2MgO8
• Relative molecular weight of Mg(ClO4)2: 223.2062
• Molar mass of Mg(ClO4)2: 223.2062 g/mol (0.22321 kg/mol)

Calculation of the relative molecular and molar mass of Mg(ClO4)2

• Mr[Mg(ClO4)2] = Ar[Cl] * 2 + Ar[Mg] + Ar[O] * 8 = 35.453 * 2 + 24.305 + 15.9994 * 8 = 223.2062
• Molar mass (kg/mol) = Mr[Mg(ClO4)2] : 1000 = 223.2062 : 1000 = 0.22321 kg/mol

Mg(ClO4)2: percent composition by element
