if 16.0 ml of acetone is dissolved in water to make 155 ml of solution, what is the concentration expressed in percent by volume of the solute?
Answer
Explanation:
Step1: Recall the formula for percent by volume
The formula for percent by volume ((v/v%)) is (\text{Percent by Volume} = \frac{\text{Volume of Solute}}{\text{Volume of Solution}} \times 100%)
Step2: Identify the values of solute and solution volume
Volume of solute (acetone) (= 16.0\space mL) Volume of solution (= 155\space mL)
Step3: Substitute the values into the formula
(\text{Percent by Volume} = \frac{16.0}{155} \times 100%) Calculate (\frac{16.0}{155} \approx 0.1032) Then (0.1032\times 100% = 10.32%)
Answer:
The concentration expressed in percent by volume of the solute is approximately (10.3%) (or (10.32%) depending on significant figures)
