Answer is: 127 grams rams of metallic copper can be obtained.

Balanced chemical reaction: 2Al + 3CuSO₄ → Al₂ (SO₄) ₃ + 3Cu.

m (Al) = 54.0 g.

n (Al) = m (Al) : M (Al).

n (Al) = 54 g : 27 g/mol.

n (Al) = 2 mol.

m (CuSO₄) = 319 g.

n (CuSO₄) = 319 g : 159.6 g/mol.

n (CuSO₄) = 2 mol; limiting reactant.

From chemical reaction: n (CuSO₄) : n (Cu) = 3 : 3 (1 : 1).

n (Cu) = 2 mol.

n (Cu) = 2 mol · 63.55 g/mol.

n (Cu) = 127.1 g.
