An analytical chemist is titrating 204.6 mL of a 0.4500M solution of hydrazoic acid (HN₂) with a 0.9500M solution of KOH. The p K of hydrazoic acid is 4.72. Calculate the pH of the acid solution after the chemist has added 39.81 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places.
