Molar and molecular weight of ZnO2

• Relative molecular weight of ZnO2: 97.4078
• Molar mass of ZnO2: 97.4078 g/mol (0.09741 kg/mol)

Calculation of the relative molecular and molar mass of ZnO2

• Mr[ZnO2] = Ar[Zn] + Ar[O] * 2 = 65.409 + 15.9994 * 2 = 97.4078
• Molar mass (kg/mol) = Mr[ZnO2] : 1000 = 97.4078 : 1000 = 0.09741 kg/mol

ZnO2: percent composition by element

• Zinc (Zn) = 65.409 : 97.4078 * 100 = 67.15 %
• Oxygen (O) = 31.9988 : 97.4078 * 100 = 32.85 %
