Answer:
The mass of ammonia gas is 36.4 grams.
Explanation:
Ammonia gas combines with excess oxygen gas to produce nitric oxide and water.
The chemical reaction is as follows.
[tex]4NH_{3}+5O_{2}\rightarrow 4NO+6H_{2}O[/tex]
The [tex]\Delta H^{o}[/tex] of the reaction is -1170 kJ.
When 363 kJ energy is released .
[tex]Moles\,of\,\,ammonia=363kJ\times (\frac{4}{1170})=1.24mols[/tex]
[tex]Mass\,of\,ammonia=Moles\times molarmass[/tex]
[tex]Mass\,of\,ammonia=0.124\times 17.03g/mol=36.4g[/tex]
Therefore, The mass of ammonia gas is 36.4 grams.
