A chemistry graduate student is given 300, ml of a 0.80M trimethylamine ((CH,) N) solution. Trimethylamine is a weak base with K-7.4 x 10. What mass of (CH,) NHCI should the student dissolve in the (CH,)N solution to turn it into a buffer with pH -11.45? You may assume that the volume of the solution doesn't change when the (CH,) NHCI is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
