Question

To completely convert 9. 0 moles of hydrogen gas (h2) to ammonia gas, how many moles of nitrogen gas (n2) are required?

Answer 1

To completely convert 9. 0 moles of hydrogen gas (h2) to ammonia gas, 3.0 moles of nitrogen gas (n2) are required.

What are moles?

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

The given reaction is $\rm N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)$

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  

$\rm Moles\; of\; nitrogen = \dfrac{9.0 }{3} =3.0\;mol$

Thus, 3.0 moles of nitrogen gas (n2) are required.
