Question

How many moles of NO is produced from 15.2 moles of oxygen gas in the presence

of excess of ammonia?
4NH3(g) +502(0) --> 4NOg+6H,00)

Answer 1

Answer : The number of moles of NO produced is 12.16 moles.

Explanation : Given,

Moles of
`O_2` = 15.2 moles

The given balanced chemical reaction is:

`4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(l)`

From the balanced chemical reaction we conclude that,

As, 5 moles of
`O_2` react to give 4 moles of NO

So, 15.2 moles of
`O_2` react to give
`(4)/(5)* 15.2=12.16` moles of NO

Therefore, the number of moles of NO produced is 12.16 moles.
