Question: You require 0.150 L of a buffer solution with pH = 3.00. On the shelf is a bottle of trichloracetic acid/sodium trichloracetate buffer with pH

You require 0.150 L of a buffer solution with pH = 3.00. On the shelf is a bottle of trichloracetic acid/sodium trichloracetate buffer with pH = 2.95. The label also says [trichloracetate ion]= 0.200 mol · L^–1. What mass of which substance (trichloracetic acid or sodium trichloracetate) should you add to 0.150 L of the buffer to obtain the desired pH?
