Question

suppose 0.65 l of acetone and 0.23 l of toluene are mixed, and the final solution has a volume of 0.898 l. note that the density of acetone is 0.78 g/ml. calculate the volume percent of acetone in this solution. be sure your answer has the right number of significant digits. % (v/v)

Explanation:

Step1: Recall the formula for volume - percent

The formula for volume - percent \((v/v)\) is \(\text{Volume}\%=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times100\%\)

Step2: Identify the volume of solute and solution

The volume of acetone (solute) \(V_{solute}=0.65\space L\), and the volume of the solution \(V_{solution}=0.898\space L\)

Step3: Calculate the volume - percent

Substitute the values into the formula:
