Choose the best answer

What volume of O₂ at STP (273 K and 1 atm) is required to burn 16 g sulfur, and what volume of SO₂ is produced? S + O₂ → SO₂

Verified Answer & Explanation⌄

Correct Answer: D) 11.2 L and 11.2 L

Concept Explanation

16 g S = 0.50 mol. The ratio S : O₂ : SO₂ = 1 : 1 : 1. Therefore: O₂ = 0.50 mol = 11.2 L SO₂ = 0.50 mol = 11.2 L.
