Problem- Since molarity is a concentration unit used mainly by chemists, the concentrations of commercial solutions are normally measured by the % of solute in the solution. Household vinegar is a 5%( by volume) solution of acetic acid in water. Assuming that the density of your vinegar is 1.0055 g /ml and the density of acetic acid is 1.05 g/mL use the molarity you measured in the experiment to determine the volume % of acetic acid in you vinegar sample. ( Molarity from experiement = 0.8284 M)
Please illustrate work and walk me during the problem so that I can follow and understand it.
