The question in the image asks: 

**What is the percentage by volume of hydrochloric acid in a solution that contains 75 mL of hydrochloric acid solution in 4.2 mL of water?**

To calculate the percentage by volume of hydrochloric acid, we use the formula:

\[
\text{Percentage by volume} = \left( \frac{\text{Volume of solute}}{\text{Volume of solution}} \right) \times 100
\]

Here:
- Volume of solute (hydrochloric acid) = 75 mL
- Volume of solvent (water) = 4.2 mL
- Total volume of solution = Volume of solute + Volume of solvent = 75 mL + 4.2 mL = 79.2 mL

Now, applying the formula:

\[
\text{Percentage by volume} = \left( \frac{75}{79.2} \right) \times 100
\]

Let's calculate this.

The percentage by volume of hydrochloric acid in the solution is approximately **94.7%**.
