Calculate the moles of ammonium phosphate produced by the reaction of of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer 1

The given question is incomplete. The complete question is:

Ammonium phosphate
`(NH_4)_3PO_4` is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid
`H_3PO_4` with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 1.7 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer: 0.57 moles of ammonium phosphate are produced by the reaction of 1.7 moles of liquid ammonia

Step-by-step explanation:

The balanced chemical equation is:

`H_3PO_4+3NH_4OH\rightarrow (NH_4)_3PO_4+3H_2O`

According to stoichiometry:

3 moles of liquid ammonia
`(NH_4OH)` produces = 1 mole of ammonium phosphate
`(NH_4)_3PO_4`

Thus 1.7 moles of liquid ammonia
`(NH_4OH)` produces =
`(1)/(3)* 1.7=0.57` mole of ammonium phosphate
`(NH_4)_3PO_4`

Thus 0.57 moles of ammonium phosphate are produced by the reaction of 1.7 moles of liquid ammonia
