A chemistry graduate student is given 500. mL of a 0.90M propanoic acid (HC₂H,CO₂) solution. Propanoic acid is a weak acid with K=1.3 x 10³. What mass of NaC₂H,CO₂ should the student dissolve in the HC₂H₂CO₂ 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 NaC₂H₂CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0
