Answer: 101.96 g
Explanation:- Molar mass is the mass of 1 mole of substance.
1 mole of [tex]Al_2O_3[/tex] contains 2 moles of Aluminium and 3 moles of Oxygen atom.
Thus mass of [tex]Al_2O_3[/tex] will be=[tex]2\times {\text {mass of 1 mole of Aluminium}}+3\times {\text {mass of 1 mole of oxygen atom}}[/tex]
Thus mass of [tex]Al_2O_3[/tex] will be[tex]=2moles\times {26.98g/mol}+3moles\times {16g/mol}=101.96g[/tex]
