Answer:

25%

Explanation:

Given: mass (solute) = 100ml ethanol

mass (solution) = 400 ml

Reqrd: % of volume of solute

Solution: Percentage = [(m solute)/(m solution)] (100)

Percentage = (100ml/400ml) 100

Percentage = 0.25 (100)

Percentage = 25 %

ANS. The percentage of volume of ethanol in the solution is 25%.
