Answer:
0.5 moles of O₂
Explanation:
See the stoichiometry of the reaction:
2CO + O₂ → 2CO₂
2 moles of carbon monoxide need 1 mol of oxygen to react in order to produce 2 moles of carbon dioxide.
If I want to produce 1 mol of CO₂, I just need the half of O₂.
You will see in this rule of three. Ratio is 2:1
2 moles of CO₂ are produced by 1 mol of O₂ (Stoichiometry - reaction)
1 mol of CO₂ will be produced by ( 1 . 1) / 2 = 0.5 moles

a. 30 moles of H₂O
b. 2.33 moles of N₂
<h3>Further explanation</h3>
Given
a. 20 moles of NH₃
b. 3.5 moles of O₂
Required
a. moles of H₂O
b. moles of N₂
Solution
Reaction
4NH₃+3O₂⇒2N₂+6H₂O
a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :
=6/4 x mol NH₃
= 6/4 x 20 moles
= 30 moles
b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :
=2/3 x mol O₂
= 2/3 x 3.5 moles
= 2.33 moles
