Multiple Choice

You are given 5.00 mL of an H₂SO₄ solution of unknown concentration. You divide the 5.00-mL sample into five 1.00-mL samples and titrate each separately with 0.1000 M NaOH. In each titration, the H₂SO₄ is completely neutralized. The average volume of NaOH solution used to reach the endpoint is 15.3 mL. What was the concentration of H₂SO₄ in the 5.00-mL sample?

• A) 0.306 M
• B) 0.765 M
• C) 3.06 M
• D) 1.53 × 10^-3 M
• E) 1.53 M
