Molar and molecular weight of CoSeO3

• Relative molecular weight of CoSeO3: 185.891395
• Molar mass of CoSeO3: 185.891395 g/mol (0.18589 kg/mol)

Calculation of the relative molecular and molar mass of CoSeO3

• Mr[CoSeO3] = Ar[Co] + Ar[Se] + Ar[O] * 3 = 58.933195 + 78.96 + 15.9994 * 3 = 185.891395
• Molar mass (kg/mol) = Mr[CoSeO3] : 1000 = 185.891395 : 1000 = 0.18589 kg/mol

CoSeO3: percent composition by element

• Cobalt (Co) = 58.933195 : 185.891395 * 100 = 31.703 %
• Selenium (Se) = 78.96 : 185.891395 * 100 = 42.476 %
• Oxygen (O) = 47.9982 : 185.891395 * 100 = 25.821 %
