scientist needs to prepare an acetate buffered solution at pH 5.0. What is the final concentration of acetic acid (pKa 4.76) and sodium acetate she needs in the solution to have a create a final concentration of 25 mM? The answers are  [Acetic acid] = 9.12 mM [acetate] = 15.88 mM but I do not know how to get to those answers.
