Answer:

D) 1.04 × 10¹ mol H₃PO₄

Explanation:

Based on the reaction:

3Hg(OH)₂ + 2H₃PO₄ → Hg₃(PO₄)₂ + 6H₂O

2 moles of phosphoric acid produce 6 moles of water. If there are produced 3.13x10¹ moles of water, the phosphoric acid moles that reacted are:

3.13x10¹ moles of water ₓ (2 moles phosphoric acid / 6 moles of water) =  1.04 × 10¹ mol H₃PO₄

Right answer is:

D) 1.04 × 10¹ mol H₃PO₄
