A chemistry graduate student is given 250. mL of a 1.00M propanoic acid (HC,H,CO₂) solution. Propanoic acid is a weak acid with K = 1.3 × 105. What mass of KC,H,CO2 should the student dissolve in the HC2H, CO2 solution to turn it into a buffer with pH = 4.33? You may assume that the volume of the solution doesn't change when the KC2H5CO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. x10
