To completely convert 9. 0 moles of hydrogen gas (h2) to ammonia gas, 3.0 moles of nitrogen gas (n2) are required.
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
The given reaction is [tex]\rm N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)[/tex]
By the stoichiometry rule of ratio hydrogen: nitrogen
3 : 1
The reacted moles of nitrogen is equals to H/3 moles of reacted hydrogen
So, moles of nitrogen
[tex]\rm Moles\; of\; nitrogen = \dfrac{9.0 }{3} =3.0\;mol[/tex]
Thus, 3.0 moles of nitrogen gas (n2) are required.
