Question

Ammonium phosphate NH43PO4 is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid H3PO4 with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 0.050mol of phosphoric acid. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

Answer:

0.050 mol

Explanation:

The reaction that takes place is:

• H₃PO₄ + 3NH₃ → (NH₄)₃PO₄

Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:

• 0.050 mol H₃PO₄ * $\frac{1mol(NH_4)_3PO_4}{1molH_3PO_4}$ = 0.050 mol (NH₄)₃PO₄

Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
