Molar and molecular weight of Al2O5Si

• Relative molecular weight of Al2O5Si: 162.0455772
• Molar mass of Al2O5Si: 162.0455772 g/mol (0.16205 kg/mol)

Calculation of the relative molecular and molar mass of Al2O5Si

• Mr[Al2O5Si] = Ar[Al] * 2 + Ar[O] * 5 + Ar[Si] = 26.9815386 * 2 + 15.9994 * 5 + 28.0855 = 162.0455772
• Molar mass (kg/mol) = Mr[Al2O5Si] : 1000 = 162.0455772 : 1000 = 0.16205 kg/mol
