1 mole $A {l}_{2} {O}_{3}$

#### Explanation:

Its a bit difficult to answer your question precisely. However lets look at the chemical reaction between Aluminium and oxygen. As you know Aluminium is a metal and oxygen is gaseous. If we write the balanced chemical reaction we have

$4 A l + 3 {O}_{2} \to 2 A {l}_{2} {O}_{3}$

If 1.5 mole Oxygen gas reacts then from the above balanced reaction we can infer that 1 mole of Aluminium oxide will be produced in a complete reaction.
