Question

17.4 mL of alcohol is dissolved in enough water to make 131 mL of solution. What is the percentage by volume of this solution? (%v/v)

Answer 1

Step-by-step explanation:

We are given: volume of alcohol = 17.4mL

: volume of solution = 131mL

`\begin{gathered} Percent\text{ by volume = }\frac{volume\text{ of alcohol}}{volume\text{ of solution}}*100 \\ \\ \text{ = }(17.4)/(131)*100 \\ \\ \text{ = 13.28\%} \end{gathered}`

Answer:

Percent by volume is 13.28%.
