An analytical chemist is titrating 181.2 mL of a 0.09000M solution of diethylamine ((CH) NH) with a 0.5400M solution of HNO3. The pK, of diethylamine
is 2.89. Calculate the pH of the base solution after the chemist has added 26.9 ml of the HNO, 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.
