Percentage by  Volume

1. Given:

    volume of solution = 205 mL

    volume of solute = 10 mL

   Find: percentage by volume

   Formula: % volume = x 100%

   Solution:

         % volume = x 100%

         % volume = x 100%

         % volume = 0.0488 x 100%

         % volume = 4.88%

   Final Answer: 4.88%

Explanation:

Mixture is a classification of matter wherein two or more substances are physically combined. A homogeneous mixture is referred to as a solution. A solution is made up of solute and solvent. The solute is the substance being dissolved by the solvent. The solution can either be unsaturated, saturated, or supersaturated. The concentration of a solution can be specifically expressed through percent by volume. The percent by volume is the ratio of the solute in a given solution, then multiplied by 100 %:

   % volume = x 100%

Percent by volume is used if the volume of solute and solvent is given. In the question, the solute is the acetic acid which is 10 mL and the solution is the vinegar, which is 205 mL. Substituting the values to the given formula will give us the percent by volume. The higher the percent by volume, the higher the concentration. In the question, there is only 4.88% acetic acid in the vinegar.
