Question

9 mol P4O₁₀ reacts with 51 mol H₂O according to the equation below:

P4O₁₀ + 6H₂O → 4H₃PO₄
How many moles of H₃PO₄ form from 9 mol P₄O₁₀?

[?} mol H₃PO₄
Round your answer to the ones place.

Answer 1

From 9 moles of P4O10, 36 moles of H3PO4 will be produced according to the balanced chemical equation.

Step-by-step explanation:

When 9 mol of P4O10 reacts with water (H2O), according to the balanced chemical equation

P4O10 + 6H2O → 4H3PO4,

the ratio of P4O10 to H3PO4 produced is 1:4.

This means that for every 1 mole of P4O10, 4 moles of H3PO4 are produced.

Therefore, if we start with 9 moles of P4O10, we will produce 4 times as many moles of H3PO4, which is 36 moles of H3PO4.
