Concisely explain how you should prepare 250. mL of a 10 mF pH 4.5 acetate buffer. Available reagents: sodium acetate (NaOAc, 82.03 g/mol, Kb = 5.56 x 10-10), 0.1 M HCl, and 0.1 M NaOH (common glassware and laboratory equipment is also available). At this pH, what is the ratio [OAc-]/[HOAc]?

Note: I did my calculation and end up with 0.205g of NaOAc + 8.92 mL NaOH needed to make the buffer, but I'm not so sure about it. Can you show me how to solve this problem in details. Thanks in advance.
