What mass of A chemistry graduate student is given 300. mL of a 0.80M benzoic acid (HC H,CO,) solution. Benzoic acid is a weak acid with K 6.3 x 10 NaC H,CO, should the student dissolve in the HC,H,CO, solution to turn it into a buffer with pH =4.51? 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.
