<-4 A chemistry graduate student is given 125. mL of a 0.40 M dimethylamine ((CH3)₂NH) solution. Dimethylamine is a weak base with K, -5.4 × 10. What mass of (CH3)₂NH₂Cl should the student dissolve in the (CH₂), NH solution to turn it into a buffer with pH = 11.18? You may assume that the volume of the solution doesn't change when the (CH3)2NH₂Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. C
