A chemistry graduate student is given 125, mL of a 0.50M benzoic acid (HC,H,CO,) solution. Benzoic acid is a weak acid with NaC, H,CO, should the student dissolve in the HC,H,CO, solution to turn it into a buffer with pH-4.177 You may assume that the volume of the solution doesn't change when the NaC,H,CO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
