Creating a buffer soltuion

1. (5 pts) You have three bottles, one filled with 1M NaAc (Sodium Acetate), one filled with 1M HAc (Acetic Acid), and one filled with distilled water. You need to create a buffer solution that has a pH of 4.75 such that when 1ml of 10M HCl is added to 100ml of your buffer, the resulting pH is 3.75 (±0.1). What concentrations of HAc and NaAc do you need to create the buffer solution?
