Explanation:
We are given: volume of alcohol = 17.4mL
: volume of solution = 131mL
[tex]\begin{gathered} Percent\text{ by volume = }\frac{volume\text{ of alcohol}}{volume\text{ of solution}}\times100 \\ \\ \text{ = }\frac{17.4}{131}\times100 \\ \\ \text{ = 13.28\%} \end{gathered}[/tex]Answer:
Percent by volume is 13.28%.
