Molar and molecular weight of Mg3(VO4)2

• Relative molecular weight of Mg3(VO4)2: 302.7932
• Molar mass of Mg3(VO4)2: 302.7932 g/mol (0.30279 kg/mol)

Calculation of the relative molecular and molar mass of Mg3(VO4)2

• Mr[Mg3(VO4)2] = Ar[Mg] * 3 + Ar[V] * 2 + Ar[O] * 8 = 24.305 * 3 + 50.9415 * 2 + 15.9994 * 8 = 302.7932
• Molar mass (kg/mol) = Mr[Mg3(VO4)2] : 1000 = 302.7932 : 1000 = 0.30279 kg/mol
