Ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with liquid ammonia. Calculate the moles of ammonia needed to produce 0.060 mol of ammonium phosphate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer:

[tex]n_{NH_3}=0.18molNH_3[/tex]

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

[tex]H_3PO_4(aq)+3NH_3(l)\rightarrow (NH_4)_3PO_4[/tex]

In such a way, considering the 3 to 1 molar relationship between ammonia and ammonium phosphate, the moles of ammonia result:

[tex]n_{NH_3}=0.060mol(NH_4)_3PO_4*\frac{3molNH_3}{1mol(NH_4)_3PO_4}\\n_{NH_3}=0.18molNH_3[/tex]

Best regards.
