3. You should include a second table that has information about the concentration of the diluted
vinegar and the concentration (and brand) of the original vinegar solution. Provide one
complete series of sample calculations. (Remember that you diluted the original vinegar by 1:10
before you performed the titration.). The molar mass of acetic acid is 60.05 g/mole and you
should assume that the density of vinegar is 1.00 g/mL. Use this information to calculate the
mass percent of acetic acid in the original vinegar solution.
