A chemistry graduate student is given 250. mL of a 0.50M trimethylamine ((CH N solution. Trimethylamine is a weak base with K,=7.4x 10. What mass of (CH NHCI should the student dissolve in the (CH,) N solution to turn it into a buffer with pH =11.09? 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.
