A chemistry graduate student is given 100. mL of a 1.00M propanoic acid (HC₂H₂CO₂) solution. Propanoic acid is a weak acid with K = 1.3 × 10¯³. What mass of KC₂ H₂CO₂ should the student dissolve in the HC₂H₂CO₂ solution to turn it into a buffer with pH = 5.39? You may assume that the volume of the solution doesn't change when the KC₂H₂CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 4.8 X S
