Molar and molecular weight of CsSeO4

• Relative molecular weight of CsSeO4: 275.8630519
• Molar mass of CsSeO4: 275.8630519 g/mol (0.27586 kg/mol)

Calculation of the relative molecular and molar mass of CsSeO4

• Mr[CsSeO4] = Ar[Cs] + Ar[Se] + Ar[O] * 4 = 132.9054519 + 78.96 + 15.9994 * 4 = 275.8630519
• Molar mass (kg/mol) = Mr[CsSeO4] : 1000 = 275.8630519 : 1000 = 0.27586 kg/mol

CsSeO4: percent composition by element
