mistry graduate student is given 450. mL of a 0.60M propanoic acid (HC,H;CO,) solution. Propanoic acid is a weak acid with K. What of KC,H;CO2 should the student dissolve in the HC,H,CO, solution to turn it into a buffer with pH =4.91? ay assume that the volume of the solution doesn't change when the KC, H,CO, is dissolved in it. Be sure your answer has a unit symbol, and round ificant digits.
