Problem: Given 10.0 grams of hydrogen gas (H₂), how many grams of water (H₂O) can be produced when it reacts completely with oxygen? The balanced reaction is: 2 H₂ + O₂ → 2 H₂O Solution Breakdown: Step 1: Convert given mass to moles - Molar mass of H₂ = 2.02 g/mol - Moles of H₂ = 10.0 g ÷ 2.02 g/mol ≈ 4.95 mol Step 2: Use mole ratio from balanced equation - The coefficients show 2 mol H₂ produce 2 mol H₂O - The ratio is 1:1 Step 3: Find moles of water produced - Moles of H₂O = Moles of H₂ × (2 mol H₂O / 2 mol H₂) = 4.95 mol Step 4: Convert moles of water to grams - Molar mass of H₂O = 18.02 g/mol - Mass of H₂O = 4.95 mol × 18.02 g/mol ≈ 89.3 g Answer: Approximately 89.3 grams of water can be produced.
