You are required to make 500 mL of a buffer solution with pH = 5.0 and a total acetate concentration of 0.1000 M. You are supplied with solid sodium actetate

(CH3COONa) and 2.00 M hydrochloric acid. What mass of sodium acetate and what volume of hydrochloric acid would you use? Show all working.
(For CH3COOH, Ka = 1.75 x 10-5)
