1. Vinegar is normally assumed to be a 5% acetic acid solution by weight (w/w) meaning that the concentration of acetic acid is 5 grams per 100 grams of solution. If you assume that the density of vinegar is 1.0 g/mL, calculate the percentage of acetic acid (w/w) in vinegar that you determined in this experiment. Determine the percent error if you assume the vinegar is exactly 5.0 grams of acetic acid per 100.0 grams of solution.
