For the balanced equation shown below, how many moles of Al will react with 98.7 moles of CuSO4

65.8 mol

Explanation:

Step 1: Write the balanced equation for the single displacement reaction

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of Al to CuSO₄ is 2:3.

Step 3: Calculate the number of moles of Al that will react with 98.7 moles of CuSO₄

98.7 mol CuSO₄ × 2 mol Al/3 mol CuSO₄ = 65.8 mol Al
