The vinegar solution you can purchase at the store is about 5% by mass acetic acid. It will be easier for you to assess your results if you convert 5% by mass acetic acid from weight percent to molarity since your experimental results will be in molarity. Show this conversion. You will need to approximate the density of the vinegar solution to complete this conversion.
