A chemistry graduate student is given 450.mL of a 0.70M benzoic acid HC6H5CO2 solution. Benzoic acid is a weak acid with =Ka×6.310−5. What mass of KC6H5CO2 should the student dissolve in the HC6H5CO2 solution to turn it into a buffer with pH =3.79? You may assume that the volume of the solution doesn't change when the KC6H5CO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
