Practice question

Given: How many grams of H₂O are produced from 10 g of H₂SO₄ in the reaction H₂SO₄ + 2NaOH -> Na₂SO₄ + 2H₂O ? (Atomic masses: H = 1, S = 32, O = 16) These values define the system as per NCERT data. Formula: Moles of H₂SO₄ = 10 / 98 ≈ 0.102 mol. This is standard NCERT relation. Substitution & Calculation: 1 mol H₂SO₄ produces 2 mol H₂O. Moles of H₂O = 0.102 × 2 ≈ 0.204 mol. Mass = 0.204 × 18 ≈ 3.67 g. Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
