A chemistry graduate student is given 500. ml. of a 1.50M diethylamine ((C,H) NH) solution. Diethylamine is a weak base with AK, -1.3 x 10, What mass of (C,H,) NH,CI should the student dissolve in the (C,H,) NH solution to turn it into a buffer with pH -11.50? You may assume that the valume of the solution doesn't change when the (C,Hs), NH,CI s dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits
