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

Answer:
1.1 g Na2SO4
Explanation:
First convert mL to L. Then multiply by the Molarity to get moles, then multiply by the molar mass to get grams.
15 mL x 1 L x 0.50 mol Na2SO4 x 142 g = 1.1 g
10^3 mL 1 L mol Na2SO4
