Question

Suppose 97.1 mL of acetone and 0.5 L of toluene are mixed, and the final solution has a volume of 0.609 L. Note that the density of acetone is 0.78 g/mL

Calculate the volume percent of acetone in this solution

Answer 1

To calculate the volume percent of acetone in the solution, divide the volume of acetone (97.1 mL) by the total volume of the final solution (609 mL) and multiply by 100. The volume percent of acetone is approximately 15.94%.

Step-by-step explanation:

To determine the volume percent of acetone in the solution when 97.1 mL of acetone is mixed with 0.5 L of toluene, and the final solution volume is 0.609 L, we use the following formula:

Volume percent = (Volume of solute / Total volume of solution) x 100%

First, note that 0.5 L of toluene is equivalent to 500 mL. Therefore, the total volume of the two liquids before mixing is 97.1 mL + 500 mL. However, after mixing them, the volume shrinks to 0.609 L, which is 609 mL.

To compute the volume percent of acetone in the solution, we use its initial volume against the final volume of the mixture.

Volume percent of acetone = (97.1 mL / 609 mL) x 100%

Volume percent of acetone = 15.94%

The volume percent of acetone in the solution is approximately 15.94%.
