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.

0.050 mol

Explanation:

The reaction that takes place is:

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

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

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
