A researcher dilutes 30.0 ml of ethanol to 300.0 ml with distilled water. what is the percentage concentration by volume of the

Len [333]

Answer: 9.09 %

Explanation:

To calculate the percentage concentration by volume, we use the formula:

$\text{Volume percent of solution}=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times 100$

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:

$\text{Volume percent of solution}=\frac{30}{30+300}\times 100=9.09\%$

Hence, the volume percent of solution will be 9.09 %.
