18.26 g of Al can be recovered.

Calculation:

The equation that follows is:

2Al₂O₃ → 2Al + 3O₂

The atomic mass of Al = 27 g

The molecular mass of Al₂O₃ = 102 g

From the stoichiometric equation, 102g of Al₂O₃ yields 54 g of Al

Therefore,

34.5 g of Al₂O₃ will give = [tex]\frac{54 (34.5)}{102}[/tex]

                                        = 18.26 g
