A chemistry graduate student is given 500. mL of a 1.60M chloroacetic acid (HCH2CICO2) solution. Chloroacetic acid is a weak acid with K = 1.3 × 103. What mass of NaCH2CICO2 should the student dissolve in the HCH2CICO₂ solution to turn it into a buffer with pH = 2.37? You may assume that the volume of the solution doesn't change when the NaCH2CICO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
