An aqueous solution of ethyl alcohol is made by transfering 1.32 mL of liquid ethyl alcohol to a 50.0 mL volumetric flask, and then adding enough water to fill the flask to the mark.
What is the volume/volume percentage of ethyl alcohol in the solution?
To determine the volume/volume percentage of ethyl alcohol in the solution, you need to know the volume of ethyl alcohol and the total volume of the solution.
Given:
Volume of ethyl alcohol = 1.32 mL
Total volume of the solution = 50.0 mL
To calculate the volume/volume percentage:
1. Divide the volume of ethyl alcohol by the total volume of the solution.
(1.32 mL / 50.0 mL) * 100
2. Multiply the result by 100 to convert it into a percentage.
(1.32 mL / 50.0 mL) * 100 = 2.64%
Therefore, the volume/volume percentage of ethyl alcohol in the solution is 2.64%.
