To completely convert 9. 0 moles of hydrogen gas (h2) to ammonia gas, 3.0 moles of nitrogen gas (n2) are required.
<h3>What are moles?</h3>The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
<h3 />The given reaction is
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
Thus, 3.0 moles of nitrogen gas (n2) are required.

Ammonia yields nitric oxide and water in the presence of oxygen. The mass of nitric acid that will be produced from 6.40 gm of oxygen is 4.8 grams.
<h3>What is mass?</h3>Mass is the product of the moles of the substance and its molar mass. it is given as,
The balanced chemical reaction is shown as:
Moles of oxygen are calculated by mass, 6.40 gm as,
From the reaction, the molar ratio of nitric oxide to oxygen is 4: 5 and is used to calculate the moles of nitric oxide as,
0.16 moles and molar mass, 30 of nitric oxide is used to calculate the mass as,
Therefore, 4.8 grams of nitric oxide will be produced.
