Molar and molecular weight of BaO4Se

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

Calculation of the relative molecular and molar mass of BaO4Se

• Mr[BaO4Se] = Ar[Ba] + Ar[O] * 4 + Ar[Se] = 137.327 + 15.9994 * 4 + 78.96 = 280.2846
• Molar mass (kg/mol) = Mr[BaO4Se] : 1000 = 280.2846 : 1000 = 0.28028 kg/mol

BaO4Se: 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 %
