Molar and molecular weight of BaSeO4

• Molecular formula: BaSeO4 or BaO4Se
• Relative molecular weight of BaSeO4: 280.2846
• Molar mass of BaSeO4: 280.2846 g/mol (0.28028 kg/mol)

Calculation of the relative molecular and molar mass of BaSeO4

• Mr[BaSeO4] = Ar[Ba] + Ar[O] * 4 + Ar[Se] = 137.327 + 15.9994 * 4 + 78.96 = 280.2846
• Molar mass (kg/mol) = Mr[BaSeO4] : 1000 = 280.2846 : 1000 = 0.28028 kg/mol

BaSeO4: percent composition by element

• Barium (Ba) = 137.327 : 280.2846 * 100 = 48.996 %
• Oxygen (O) = 63.9976 : 280.2846 * 100 = 22.833 %
• Selenium (Se) = 78.96 : 280.2846 * 100 = 28.171 %
