Answer : The number of moles of NO produced is 12.16 moles.
Explanation : Given,
Moles of [tex]O_2[/tex] = 15.2 moles
The given balanced chemical reaction is:
[tex]4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(l)[/tex]
From the balanced chemical reaction we conclude that,
As, 5 moles of [tex]O_2[/tex] react to give 4 moles of NO
So, 15.2 moles of [tex]O_2[/tex] react to give [tex]\frac{4}{5}\times 15.2=12.16[/tex] moles of NO
Therefore, the number of moles of NO produced is 12.16 moles.
