Answer : The number of moles of NO produced is 12.16 moles.
Explanation : Given,
Moles of 
 = 15.2 moles
 = 15.2 moles
The given balanced chemical reaction is:

From the balanced chemical reaction we conclude that,
As, 5 moles of 
 react to give 4 moles of NO
 react to give 4 moles of NO
So, 15.2 moles of 
 react to give
 react to give 
 moles of NO
 moles of NO
Therefore, the number of moles of NO produced is 12.16 moles.
