Molar and molecular weight of AlOSi

• Relative molecular weight of AlOSi: 71.0664386
• Molar mass of AlOSi: 71.0664386 g/mol (0.07107 kg/mol)

Calculation of the relative molecular and molar mass of AlOSi

• Mr[AlOSi] = Ar[Al] + Ar[O] + Ar[Si] = 26.9815386 + 15.9994 + 28.0855 = 71.0664386
• Molar mass (kg/mol) = Mr[AlOSi] : 1000 = 71.0664386 : 1000 = 0.07107 kg/mol

AlOSi: percent composition by element

• Aluminum (Al) = 26.9815386 : 71.0664386 * 100 = 37.967 %
• Oxygen (O) = 15.9994 : 71.0664386 * 100 = 22.513 %
• Silicon (Si) = 28.0855 : 71.0664386 * 100 = 39.52 %
