A chemistry graduate student is given 250. mL of a 0.50M nitrous acid (HNO₂) solution. Nitrous acid is a weak acid with K =4.5 × 10 should the student dissolve in the HNO₂ solution to turn it into a buffer with pH = 2.91? 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. 0 X 3 What mass of KNO₂ ?
