Explanation:
No of molecules = no of moles × Avogadro's number
No of moles = No of molecules / Avogadro's number
Number of moles = 5.4×10^23/6.02×10^23
Number of moles = 0.897 moles of Al2O3
Number of moles = mass in gram / molar mass
Mass in gram = number of moles× molar mass
Mass in gram = 0.897× 102
91.49 grams
