Hi,

I have a quiz for my Chemistry class, and I was able to answer them all except for this last problem:

A titration was performed on vinegar (acetic acid) to determine it’s molar concentration. Sodium Hydroxide was added to reach the equivalence point and the following data was collected. 
150 ml of vinegar with unknown molarity was titrated.
45.5 ml of .5 M NaOH was added to reach equivalence point.
Determine the Molarity of the vinegar.

I am really confused as to how to solve this problem, so any help on where to start would be really helpful. Thanks!

Simple stoichiometry. Start with the reaction equation.
