Please teach me how to solve this problem. There still more questions that I must answer similar to this:

To buffer a solution at a pH of 4.57, what mass of sodium acetate (NaCH3COO) should you add o 500mL of a 0.150M solution of acetic acid (CH3COOH)?

Can someone please show the steps. I got 3.66g NaCH₃COO as my answer. I just want to know if its correct, and if not, what is the correct answer.

Seems reasonable. What are your steps?
