A chemistry graduate student is given 500. mL of a 0.90 M dimethylamine ((CH3)₂NH) solution. Dimethylamine is a weak base with K, -5.4 × 10. What mass of (CH₂)₂NH₂Br should the student dissolve in the (CH₂), NH solution to turn it into a buffer with pH -10.87? You may assume that the volume of the solution doesn't change when the (CH3)₂NH₂ Br is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
