. What mass of A chemistry graduate student is given 450 mL of a 0.90 M pyridine (CHN) solution. Pyridine is a weak base with K, -1.7*10 CH NHCI should the student dissolve in the CHN solution to turn it into a buffer with pH = 5.007 You may assume that the volume of the solution doesn't change when the C H NHCl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2...
