__ CaSO4 + ____AIP --&gt; ____Ca3P2 + ____AI2(SO4)3
4vir4ik [10]

Answer:

4.89 mol

Explanation:

Step 1: Write the balanced equation

This is a double displacement reaction.

3 CaSO₄ + 2 AIP ⇒ Ca₃P₂ + AI₂(SO₄)₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CaSO₄ to AlP is 3:2.

Step 3: Calculate the moles of AlP needed to react with 7.33 moles of CaSO₄

We will use the previously established molar ratio.

7.33 mol CaSO₄ × 2 mol AlP/3 mol CaSO₄ = 4.89 mol AlP
