Chemistry titration lab of vinegar- What do I do?

45.6ml of .1M NaOH titrant was added to 100ml D.I. water, 5ml vinegar, and phenolphthalein to see the color change to pink. I need to find the concentration of acetic acid in the vinegar, and the % (wt/wt). I think I'm allowed to assume the Ka of the vinegar is 1.8E-5 and the density is 1.01g/ml. I know how to find the moles of NaOH dispensed, but then what?
