A chemistry graduate student is given 100. mL of a 0.60M dimethylamine ((CH) NH) solution. Dimethylamine is a weak base with K=5.4 × 10. What mass of (CH,) NH,Br should the student dissolve in the (CH,) NH solution to turn it into a buffer with pH =11.05? You may assume that the volume of the solution doesn't change when the" (CH,) NH,Br is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
