== A chemistry graduate student is given 125. mL of a 0.90M acetic acid (HCH3CO2) solution. Acetic acid is a weak acid, with Ka = 1.8 × 10 NaCH3CO2 should the student dissolve in the HCH,CO, solution to turn it into a buffer with pH = 4.90? == You may assume that the volume of the solution doesn't change when the NaCH, CO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
