Weak Acid Strong Base Titrations

Q. The active ingredient in aspirin is acetylsalicylic acid. A 2.57 g sample of acetylsalicylic acid required 26.96 mL of 0.5292 M NaOH for complete reaction. Addition of 15.58 mL of 0.4580 M HCl to the flask containing the aspirin and the sodium hydroxide produced a mixture with pH = 3.48. Find the Ka value of Acetylsalicylic acid is a monoprotic acid.
