An analytical chemist is titrating 123.0 mL of a 0.1500M solution of dimethylamine ((CH3)₂NH) with a 0.1200M solution of HNO3. The p K₂ of dimethylamine is 3.27. Calculate the pH of the base solution after the chemist has added 84.5 mL of the HNO3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added. Round your answer to 2 decimal places.
