Molar and molecular weight of BaS2O3

• Relative molecular weight of BaS2O3: 249.4552
• Molar mass of BaS2O3: 249.4552 g/mol (0.24946 kg/mol)

Calculation of the relative molecular and molar mass of BaS2O3

• Mr[BaS2O3] = Ar[Ba] + Ar[S] * 2 + Ar[O] * 3 = 137.327 + 32.065 * 2 + 15.9994 * 3 = 249.4552
• Molar mass (kg/mol) = Mr[BaS2O3] : 1000 = 249.4552 : 1000 = 0.24946 kg/mol
