The number of moles of Al needed to react with each mole of CuSO₄ in the reaction 2Al + 3CuSO₄ $\rarr$ 3 Cu + Al₂(SO₄)₃ is

Question

Quizplus · Accepted Answer

From the balanced chemical equation, we can see that 2 moles of Al react with 3 moles of CuSO₄. Thus, the ratio of moles of Al needed to react with each mole of CuSO₄ is: 2 moles Al : 3 moles CuSO₄ 1 mole Al : (3/2) moles CuSO₄ Therefore, for each mole of CuSO₄, we need (2/3) moles of Al. So the answer is: 1 mole CuSO₄ : (2/3) mole Al Therefore, the answer is C: 2/3.
