Answer:

v_{solute}=25mL

Explanation:

Hello there!

In this case, according to the by-volume concentration of this solution, it is possible for us to use its mathematical definition as shown below:

\%v=\frac{v_{solute}}{v_{solution}}*100\%

Thus, given the percent and the volume of the solution, we can solve for the volume of ethanol (solute) as shown below:

v_{solute}=\frac{\%v*v_{solution}}{100\% }\\\\v_{solute}=\frac{5.00\%*500mL}{100\%}\\\\ v_{solute}=25mL

Best regards!
