[tex]\tt{\huge{\red{Solution:}}}[/tex]
Step 1: List the given values.
[tex]\begin{aligned} & \text{volume of solution} = \text{250 mL} \\ & \text{percent by volume} = 15\% \end{aligned}[/tex]
Step 2: Calculate the volume of solute (HCl).
[tex]\begin{aligned} \text{volume of solute} & = \frac{\text{percent by volume}}{100\%} \times \text{volume of solution} \\ & = \frac{15\%}{100\%} \times \text{250 mL} \\ & = \text{37.5 mL} \end{aligned}[/tex]
Final Step: Calculate the volume of solvent (water).
[tex]\begin{aligned} \text{volume of solvent} & = \text{volume of solution} - \text{volume of solute} \\ & = \text{250 mL} - \text{37.5 mL} \\ & = \boxed{\text{212.5 mL}} \end{aligned}[/tex]
Hence, the volume of water present is 212.5 mL.
