A chemistry graduate student is given 250. mL of a 0.60 M pyridine (C5H5N) solution. Pyridine is a weak base with Kb = 1.7 x 10-9. What mass of C5H5NHCl should the student dissolve in the C5H5N solution to turn it into a buffer with pH = 5.33? You may assume that the volume of the solution doesn't change when C5H5NHCl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
