Answer :
Answer:
Solute = 5 mL; solution = 250 mL
Explanation:
The formula for percent by volume is
[tex]\text{Percent by volume} = \dfrac{\text{Volume of solute}}{\text{Volume of solution}}\times 100 \, \%[/tex]
If you have 250 mL of a solution that is 2 % v/v,
[tex]\begin{array}{rcl}2 \, \% & = & \dfrac{\text{Volume of solute}}{\text{250 mL}}\times 100 \, \%\\\\2 \times \text{ 250 mL} & = & \text{Volume of solute} \times 100\\\text{Volume of solute} & = & \dfrac{2 \times 250\text{ mL}}{100}\\\\ & = & \textbf{5 mL}\\\end{array}[/tex]
If there is no change of volume on mixing,
Volume of solution = 250 mL
-Volume of solute = 5
Volume of solvent = 245 mL
