<u>Answer:</u> The mass of nitric oxide is 12.72 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of ammonia = 8.00 g
Molar mass of ammonia = 17 g/mol
Putting values in equation 1, we get:
Given mass of oxygen gas = 17.0 g
Molar mass of oxygen gas = 32 g/mol
Putting values in equation 1, we get:
The given chemical reaction follows:
By Stoichiometry of the reaction:
5 moles of oxygen gas reacts with 4 moles of ammonia
So, 0.53 moles of oxygen gas will react with = of ammonia
As, given amount of ammonia is more than the required amount. So, it is considered as an excess reagent.
Thus, oxygen gas is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
5 moles of oxygen gas produces 4 moles of NO
So, 0.53 moles of oxygen gas will produce = of NO
Now, calculating the mass of NO from equation 1, we get:
Molar mass of NO = 30 g/mol
Moles of NO = 0.424 moles
Putting values in equation 1, we get:
Hence, the mass of nitric oxide is 12.72 grams
