Molar and molecular weight of BaSeO3

• Relative molecular weight of BaSeO3: 264.2852
• Molar mass of BaSeO3: 264.2852 g/mol (0.26429 kg/mol)

Calculation of the relative molecular and molar mass of BaSeO3

• Mr[BaSeO3] = Ar[Ba] + Ar[Se] + Ar[O] * 3 = 137.327 + 78.96 + 15.9994 * 3 = 264.2852
• Molar mass (kg/mol) = Mr[BaSeO3] : 1000 = 264.2852 : 1000 = 0.26429 kg/mol
