Sorry. The title should read finding volume with little information. Humongous typo :)
Suppose you are given 0.50 liter of 0.500 M acetic acid, and 0.50 liter of 0.250 liter sodium acetate. What is the maximum volume of buffer solution that you can make if the buffer must have a pH of 4.58? Ka for acetic acid is 1.8 x 10-5
pH=pKa + log([A-]/[HA])
I've gotten up to this point so far,
0.69= [A-]/[HA]
0.69= (0.125/x)/(0.25/x)
What I don't know is how I should go about from here to get the volume(x).
