What A chemistry graduate student is given 250. mL of a 0.40 M dimethylamine (CH), NH solution. Dimethylamine is a weak base with K -5.4 x 10 mass of (CH), NH,CI should the student dissolve in the (CH), NH solution to turn it into a buffer with pH 10.327 You may assume that the volume of the solution doesn't change when the (CH), NH,Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to...
