A chemistry graduate student is given 450. mL of a 0.90 M nitrous acid (HNO2) solution. Nitrous acid is a weak acid with K-4.5x10 . What mass o KNO2 should the student dissolve in the HNO2 solution to turn it into a buffer with pH-3.20? You may assume that the volume of the solution doesn't change when the KNO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
