Molar and molecular weight of ZrO2

• Molecular formula: ZrO2 or O2Zr
• Relative molecular weight of ZrO2: 123.2228
• Molar mass of ZrO2: 123.2228 g/mol (0.12322 kg/mol)

Calculation of the relative molecular and molar mass of ZrO2

• Mr[ZrO2] = Ar[O] * 2 + Ar[Zr] = 15.9994 * 2 + 91.224 = 123.2228
• Molar mass (kg/mol) = Mr[ZrO2] : 1000 = 123.2228 : 1000 = 0.12322 kg/mol

ZrO2: percent composition by element

• Oxygen (O) = 31.9988 : 123.2228 * 100 = 25.968 %
• Zirconium (Zr) = 91.224 : 123.2228 * 100 = 74.032 %
