Question

A chemistry graduate student is given 125. mL of a 0.40 M dimethylamine ((CH3)₂NH) s solution. Dimethylamine is a weak base with K-5.4×10. What
mass of (CH3)2NH₂ CI should the student dissolve in the (CH3)₂NH 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.
