How many grams of solid NaC2H3O2•3H2O (MW 136.09 g/mol) must be added to 0.300 L of a 0.50-M acetic acid (HC2H3O2) solution to give a buffer with a pH of 5.00? Assume a negligible change in volume as the solid is added. The pKa for acetic acid is 4.76. (Hint: What is the ratio of conjugate base (C2H3O2-) to acid (HC2H3O2) needed to make this buffer?)
