Answer:

0.3 moles of aluminum

Explanation:

The reaction of Aluminium with copper sulfate reacts to give aluminium sulfate and copper metal ,

The balanced chemical reaction is as follows -

2Al + 2 CuSO4 ----> Al2(SO4)3 + 3Cu

From the above balanced equation ,

considering the stoichiometry ,

3 mole of Copper  is produced , by using 2 moles of Aluminium,

using unitary method ,

hence,

1 mole of copper is produced , by using 2/3 moles of Aluminum ,

(from the question , 0.45 moles of copper )

Therefore ,

0.45 mole of copper is produced , by using 2/3 * 0.45 mole Aluminium,

Solving,

2/3 * 0.45 mole = 0.3 mol

Hence,

0.3 moles of aluminum will be required to produce, 0.45 moles of copper metal.
