Molar and molecular weight of ZnSeO3

• Molecular formula: ZnSeO3 or O3SeZn
• Relative molecular weight of ZnSeO3: 192.3672
• Molar mass of ZnSeO3: 192.3672 g/mol (0.19237 kg/mol)

Calculation of the relative molecular and molar mass of ZnSeO3

• Mr[ZnSeO3] = Ar[O] * 3 + Ar[Se] + Ar[Zn] = 15.9994 * 3 + 78.96 + 65.409 = 192.3672
• Molar mass (kg/mol) = Mr[ZnSeO3] : 1000 = 192.3672 : 1000 = 0.19237 kg/mol

ZnSeO3: percent composition by element

• Oxygen (O) = 47.9982 : 192.3672 * 100 = 24.951 %
• Selenium (Se) = 78.96 : 192.3672 * 100 = 41.046 %
• Zinc (Zn) = 65.409 : 192.3672 * 100 = 34.002 %
