A chemistry graduate student is given 125.mL of a 0.60M chlorous acid HClO2 solution. Chlorous acid is a weak acid with Ka= 1.1*10^-2. What mass of NaClO2 should the student dissolve in the HClO2 solution to turn it into a buffer with pH =1.47?

You may assume that the volume of the solution doesn't change when the NaClO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
