A chemistry graduate student is given 125. mL of a 0.30M pyridine (C₂H₂N) solution. Pyridine is a weak base with K, = 1.7 x 10. What mass of CH₂NHBr should the student dissolve in the C-H₂N solution to turn it into a buffer with pH = 4.97? You may assume that the volume of the solution doesn't change when the C-H5NHBr is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0 0x10 X 3
