A chemistry graduate student is given 300. mL of a 0.80M acetic acid (HCH,Co,) solution. Acetic acid is a weak acid with K.=1.8 × 10. What mass of KCH,CO, should the student dissolve in the HCH,Co, solution to turn it into a buffer with pH = 4.26? You may assume that the volume of the solution doesn't change when the KCH,CO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
