Molar and molecular weight of AlO

• Relative molecular weight of AlO: 42.9809386
• Molar mass of AlO: 42.9809386 g/mol (0.04298 kg/mol)

Calculation of the relative molecular and molar mass of AlO

• Mr[AlO] = Ar[Al] + Ar[O] = 26.9815386 + 15.9994 = 42.9809386
• Molar mass (kg/mol) = Mr[AlO] : 1000 = 42.9809386 : 1000 = 0.04298 kg/mol

AlO: percent composition by element

• Aluminum (Al) = 26.9815386 : 42.9809386 * 100 = 62.776 %
• Oxygen (O) = 15.9994 : 42.9809386 * 100 = 37.224 %
