What is the pH of a solution that is 0.150 M in acetic solution and 0.300 M in sodium acetate? The Ka of acetic acid is 1.8 x 10^-5.
My work:
pH= pKa + log (base/acid)
pH= -log (1.8 x 10^-5) + log (0.300/0.150)
pH=5

I would not throw away the places after 5 that are eligible to be retained. I came up with 5.04 to three significant figures.
