A solution of ethanol, C₂H₅OH, is prepared by dissolving 25.0 mL of ethanol in enough water to give a total volume of 250.0 mL. What is the percent-by-volume concentration of ethanol? A)10.0% B)9.09% C)90.0% D)1.00% E)225%

Question

Quizplus · Accepted Answer

The percent-by-volume concentration is calculated by dividing the volume of ethanol by the total volume of the solution and multiplying by 100. (25.0 mL / 250.0 mL) * 100 = 10.0%.
