Molar and molecular weight of Ba(AsO3)2

• Relative molecular weight of Ba(AsO3)2: 383.1666
• Molar mass of Ba(AsO3)2: 383.1666 g/mol (0.38317 kg/mol)

Calculation of the relative molecular and molar mass of Ba(AsO3)2

• Mr[Ba(AsO3)2] = Ar[Ba] + Ar[As] * 2 + Ar[O] * 6 = 137.327 + 74.9216 * 2 + 15.9994 * 6 = 383.1666
• Molar mass (kg/mol) = Mr[Ba(AsO3)2] : 1000 = 383.1666 : 1000 = 0.38317 kg/mol
