Molar and molecular weight of Mg(VO3)2

• Molecular formula: Mg(VO3)2 or MgO6V2
• Relative molecular weight of Mg(VO3)2: 222.1844
• Molar mass of Mg(VO3)2: 222.1844 g/mol (0.22218 kg/mol)

Calculation of the relative molecular and molar mass of Mg(VO3)2

• Mr[Mg(VO3)2] = Ar[Mg] + Ar[O] * 6 + Ar[V] * 2 = 24.305 + 15.9994 * 6 + 50.9415 * 2 = 222.1844
• Molar mass (kg/mol) = Mr[Mg(VO3)2] : 1000 = 222.1844 : 1000 = 0.22218 kg/mol

Mg(VO3)2: percent composition by element
