ΝΗ A chemistry graduate student is given 500. mL of a 0.50M diethylamine ((C₂H₂)₂NH) solution. Diethylamine is a weak base with K₂=1.3 × 10³. What mass of (C₂H₂)₂NH₂Cl should the student dissolve in the (C₂H5) NH solution to turn it into a buffer with pH = 11.27? You may assume that the volume of the solution doesn't change when the (C₂H₂)₂NH₂Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. [] x10 X
