Molar and molecular weight of Al2O2

• Relative molecular weight of Al2O2: 85.9618772
• Molar mass of Al2O2: 85.9618772 g/mol (0.08596 kg/mol)

Calculation of the relative molecular and molar mass of Al2O2

• Mr[Al2O2] = Ar[Al] * 2 + Ar[O] * 2 = 26.9815386 * 2 + 15.9994 * 2 = 85.9618772
• Molar mass (kg/mol) = Mr[Al2O2] : 1000 = 85.9618772 : 1000 = 0.08596 kg/mol

Al2O2: percent composition by element

• Aluminum (Al) = 53.9630772 : 85.9618772 * 100 = 62.776 %
• Oxygen (O) = 31.9988 : 85.9618772 * 100 = 37.224 %
