Molar and molecular weight of CaSeO3

• Relative molecular weight of CaSeO3: 167.0362
• Molar mass of CaSeO3: 167.0362 g/mol (0.16704 kg/mol)

Calculation of the relative molecular and molar mass of CaSeO3

• Mr[CaSeO3] = Ar[Ca] + Ar[Se] + Ar[O] * 3 = 40.078 + 78.96 + 15.9994 * 3 = 167.0362
• Molar mass (kg/mol) = Mr[CaSeO3] : 1000 = 167.0362 : 1000 = 0.16704 kg/mol

CaSeO3: percent composition by element

• Calcium (Ca) = 40.078 : 167.0362 * 100 = 23.994 %
• Selenium (Se) = 78.96 : 167.0362 * 100 = 47.271 %
• Oxygen (O) = 47.9982 : 167.0362 * 100 = 28.735 %
