Molar and molecular weight of Al2MgO4

• Relative molecular weight of Al2MgO4: 142.2656772
• Molar mass of Al2MgO4: 142.2656772 g/mol (0.14227 kg/mol)

Calculation of the relative molecular and molar mass of Al2MgO4

• Mr[Al2MgO4] = Ar[Al] * 2 + Ar[Mg] + Ar[O] * 4 = 26.9815386 * 2 + 24.305 + 15.9994 * 4 = 142.2656772
• Molar mass (kg/mol) = Mr[Al2MgO4] : 1000 = 142.2656772 : 1000 = 0.14227 kg/mol
