A chemistry graduate student is given 100. mL of a 0.10M dimethylamine ((CH3)2NH) solution. Dimethylamine is a weak base with K, = 5.4 × 104. What mass of (CH3)2NH2Cl should the student dissolve in the (CH3)2NH solution to turn it into a buffer with pH = 11.21? 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. ☐ x10 Ar
