Choose the best answer

What volume of CO₂ at STP (273 K and 1 atm) is produced by complete combustion of 7 g C₂H₄? C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

Verified Answer & Explanation⌄

Correct Answer: C) 11.2 dm³

Concept Explanation

7 g C₂H₄ = 7/28 = 0.25 mol. 0.25 mol C₂H₄ produces 0.50 mol CO₂. Volume = 0.50 × 22.4 = 11.2 dm³.
