To find the concentration of the sulfuric acid (H₂SO₄) solution, we can use the concept of stoichiometry and the balanced chemical equation provided:
From the balanced equation, we see that one mole of sulfuric acid reacts with two moles of sodium hydroxide (NaOH).First, calculate the moles of NaOH used in the titration:
Since it takes 2 moles of NaOH to neutralize 1 mole of H₂SO₄, the moles of H₂SO₄ can be calculated as:
Next, calculate the concentration of the H₂SO₄ solution:
Therefore, the concentration of the H₂SO₄ solution is approximately 0.1027 M.
