An analytical chemist is titrating 118.2mL of a 0.3800M solution of methylamine CH3NH2 with a 0.6300M solution of HNO3. The pKb of methylamine is 3.36. Calculate the pH of the base solution after the chemist has added 54.0mL 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.
