To calculate the volume/volume percent (v/v %) of the ethanol solution, you can use the following formula:
\[
\text{v/v \%} = \left( \frac{\text{Volume of solute}}{\text{Total volume of solution}} \right) \times 100
\]
In this case:
- Volume of ethanol (solute) = 25 mL
- Total volume of the solution = 200 mL
Now, substitute the values into the formula:
\[
\text{v/v \%} = \left( \frac{25 \, \text{mL}}{200 \, \text{mL}} \right) \times 100
\]
Calculating this gives:
\[
\text{v/v \%} = \left( 0.125 \right) \times 100 = 12.5 \%
\]
Thus, the volume/volume percent solution is **12.5 %**.
Final answer (with 3 significant digits): **12.5**
