Question

How many moles of H3PO4 would produce 12 moles of water in this reaction? ЗKOH + H3PO4 K3PO4 + 3H20

Answer 1

Answer:4 moles of H₃PO₄

Explanation: did the test homie

Answer 2

Answer:

4 moles of H₃PO₄

Explanation:

The reaction expression is given as;

     3KOH   + H₃PO₄   →   K₃PO₄   +  3H₂O

Number of moles of water  =  12moles

Unknown:

Number of moles of H₃PO₄ = ?

Solution:

 From the balanced reaction expression we see that;

          3 moles of water is produced from 1 mole of H₃PO₄

So;    12 moles of water would be produced from $\frac{12}{3}$ = 4 moles of H₃PO₄
