Use the Hendersоn-Hаsselbаlch equаtiоn tо find the concentration (in mM) of potassium acetate in a buffer containing 150 mM acetic acid if the pH is 4.98.  Ka = 1.8 x 10-5. If no work is submitted for this problem, there will be a penalty of 50%. This means a correct answer for a 5 pt problem with no work is worth a maximum of 2.5 pts.
