Quizplus · Accepted Answer

To find the molarity of the NaOH solution, use the neutralization reaction: H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O. Calculate moles of H₂SO₄ (0.355 M * 0.0282 L = 0.010011 mol). Since the ratio is 1:2, moles of NaOH = 2 * 0.010011 mol = 0.020022 mol. Molarity of NaOH = moles/volume = 0.020022 mol / 0.025 L = 0.80088 M, approximately 0.801 M.
