Molar and molecular weight of CdSeO3

• Relative molecular weight of CdSeO3: 239.3692
• Molar mass of CdSeO3: 239.3692 g/mol (0.23937 kg/mol)

Calculation of the relative molecular and molar mass of CdSeO3

• Mr[CdSeO3] = Ar[Cd] + Ar[Se] + Ar[O] * 3 = 112.411 + 78.96 + 15.9994 * 3 = 239.3692
• Molar mass (kg/mol) = Mr[CdSeO3] : 1000 = 239.3692 : 1000 = 0.23937 kg/mol

CdSeO3: percent composition by element

• Cadmium (Cd) = 112.411 : 239.3692 * 100 = 46.961 %
• Selenium (Se) = 78.96 : 239.3692 * 100 = 32.987 %
• Oxygen (O) = 47.9982 : 239.3692 * 100 = 20.052 %
