An analytical chemist is titrating 218.4 mL of a 0.1800 M solution of isopropylamine ((CH_3)_2 CHNH_2) with a 0.7600 M solution of HNO_3. The pK_b of isopropylamine is 3.33. Calculate the pH of the base solution after the chemist has added 20.9 mL of the HNO_3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO_3 solution added. Round your answer to 2 decimal places.
