Determine the volume percent of touline

Question

in a solution made by mixing 40.0ML toluene with 75. 0 ml of benzene.

Answer 1

To determine the volume percent of toluene in the solution, we need to first calculate the total volume of the solution.

Total volume of solution = volume of toluene + volume of benzene
Total volume of solution = 40.0 mL + 75.0 mL
Total volume of solution = 115.0 mL

Now we can calculate the volume percent of toluene:

Volume percent of toluene = (volume of toluene / total volume of solution) x 100%

Volume percent of toluene = (40.0 mL / 115.0 mL) x 100%
Volume percent of toluene = 34.8%

Therefore, the solution made by mixing 40.0 mL toluene with 75.0 mL benzene has a volume percent of toluene of 34.8%.
