Vinegars can be 5-20% acetic acid solutions and has been used for medicinal purposes for thousands of years. If a person takes 30 mL of vinegar a day and the molarity of the vinegar is 0.84 M, then how many grams of acetic acid (HC2H3O2) will be consumed?

The mass of acetic acid that will be consumed is 1.512 g.

Explanation:

Molarity is defined as the moles of solute present per liter of the solution.

The formula used to calculate the molarity of the solution is:

                       OR

         ......(1)

Given values:

Molarity of acetic acid = 0.84 M

Volume of solution = 30 mL

Molar mass of acetic acid = 60 g/mol

Plugging values in equation 1:

Hence, the mass of acetic acid that will be consumed is 1.512 g.
