A chemistry graduate student is given 250. mL of a 0.10M acetic acid (HCH3CO2) solution. Acetic acid is a weak -5 with K = 1.8 × 10. What mass of KCH3CO2 should the student dissolve in the HCH3CO2 solution to turn it buffer with pH = 4.92? You may assume that the volume of the solution doesn't change when the KCH3CO2 is dissolved in it. Be sure you has a unit symbol, and round it to 2 significant digits. Ar
