Answer:
112 mL
Explanation:
The formula for percent by volume is
![\text{Percent by volume} = \dfrac{\text{Volume of solute}}{\text{Volume of solution}}\times 100 \, \%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20by%20volume%7D%20%3D%20%5Cdfrac%7B%5Ctext%7BVolume%20of%20solute%7D%7D%7B%5Ctext%7BVolume%20of%20solution%7D%7D%5Ctimes%20100%20%5C%2C%20%5C%25)
If you have 250 mL of a solution that is 44.8 % v/v,
![\begin{array}{rcl}44.8\, \% & = & \dfrac{\text{Volume of solute}}{\text{250 mL}}\times 100 \, \%\\\\44.8 \times \text{ 250 mL} & = & \text{Volume of solute} \times 100\\\text{Volume of solute} & = & \dfrac{44.8 \times 250\text{ mL}}{100}\\\\ & = & \textbf{112 mL}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D44.8%5C%2C%20%5C%25%20%26%20%3D%20%26%20%5Cdfrac%7B%5Ctext%7BVolume%20of%20solute%7D%7D%7B%5Ctext%7B250%20mL%7D%7D%5Ctimes%20100%20%5C%2C%20%5C%25%5C%5C%5C%5C44.8%20%5Ctimes%20%5Ctext%7B%20250%20mL%7D%20%26%20%3D%20%26%20%5Ctext%7BVolume%20of%20solute%7D%20%5Ctimes%20100%5C%5C%5Ctext%7BVolume%20of%20solute%7D%20%26%20%3D%20%26%20%5Cdfrac%7B44.8%20%5Ctimes%20250%5Ctext%7B%20mL%7D%7D%7B100%7D%5C%5C%5C%5C%20%26%20%3D%20%26%20%5Ctextbf%7B112%20mL%7D%5C%5C%5Cend%7Barray%7D)
