101.96 g

Explanation:- Molar mass is the mass of 1 mole of substance.

1 mole of Al_2O_3 contains 2 moles of Aluminium and 3 moles of Oxygen atom.

Thus mass of Al_2O_3 will be= $2\times {\text {mass of 1 mole of Aluminium}}+3\times {\text {mass of 1 mole of oxygen atom}}$

Thus mass of Al_2O_3 will be $=2moles\times {26.98g/mol}+3moles\times {16g/mol}=101.96g$
