<u>Answer:</u> The amount of nitrogen gas produced is 3.864 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of = 6.00 g
Molar mass of = 65 g/mol
Putting values in equation 1, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
2 moles of produces 3 moles of nitrogen gas
So, 0.092 moles of will produce =
of nitrogen gas
Now, calculating the mass of nitrogen gas by using equation 1, we get:
Molar mass of nitrogen gas = 28 g/mol
Moles of nitrogen gas = 0.138 moles
Putting values in equation 1, we get:
Hence, the amount of nitrogen gas produced is 3.864 grams
