Answer: 9.09 %
Explanation:
To calculate the percentage concentration by volume, we use the formula:
[tex]\text{Volume percent of solution}=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times 100[/tex]
Volume of ethanol (solute) = 30 ml
Volume of water (solvent) = 300 ml
Volume of solution= volume of solute + volume of solution = 30+ 300 = 330 ml
Putting values in above equation, we get:
[tex]\text{Volume percent of solution}=\frac{30}{30+300}\times 100=9.09\%[/tex]
Hence, the volume percent of solution will be 9.09 %.
