Choose the best answer

If 16 g O₂ reacts with excess C₂H₆, what mass of CO₂ is formed? 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Verified Answer & Explanation⌄

Correct Answer: B) 13 g

Concept Explanation

16 g O₂ = 0.50 mol. 7 mol O₂ produce 4 mol CO₂. CO₂ formed = (4/7) × 0.50 ≈ 0.286 mol. Mass ≈ 0.286 × 44 ≈ 12.6 g ≈ 13 g.
