A chemistry graduate student is given 450, mL of a 0.50M trimethylamine ((CH,), N) solution. Trimethylamine is a weak base with K, -7.4 × 10. What (CH),NHCI should the student dissolve in the (CH), N solution to turn it into a buffer with pH=10.44? You may assume that the volume of the solution doesn't change when the (CH3), NHCI is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. X
