Answer: The moles of nitrogen and hydrogen gas formed are 0.261 moles and 0.783 moles respectively.
Explanation:
We are given:
Moles of ammonia = 0.261 moles
The chemical equation for the decomposition of ammonia follows:
[tex]2NH_3\rightarrow N_2+3H_2[/tex]
By Stoichiometry of the reaction:
2 moles of ammonia produces 1 mole of nitrogen gas and 3 moles of hydrogen gas
So, 0.261 moles of ammonia will produce [tex](1\times 0.261)=0.261[/tex] moles of nitrogen gas and [tex](3\times 0.261)=0.783[/tex] moles of hydrogen gas
Hence, the moles of nitrogen and hydrogen gas formed are 0.261 moles and 0.783 moles respectively.
