Question

How many moles of H3PO4 are produced when 3 moles P4O10 reacts completely to form H3PO4?
 P4O10(s)+6H2O(l) -->4H3PO4(aq)

Answer 1

12 moles of H₃PO₄

Explanation:

Given parameters:

Number of moles of P₄O₁₀ = 3moles

Unknown:

Number of moles of H₃PO₄ produced = ?

Solution:

This is a simple stoichiometric problem that would be solved by working from the known to the unknown substances.

The known is the number of moles of reacting P₄O₁₀.

We should establish how it relates with the unknown product and solve the problem.

     P₄O₁₀    +      6H₂O     →     4H₃PO₄

 This is a balance equation;

     From the equation;

    1 mole of P₄O₁₀  will react completely to produce 4 moles of H₃PO₄

    3 moles of P₄O₁₀  will produce 3 x 4 = 12 moles of H₃PO₄
