Expert Solution
Step 1
Raoult's Law states that vapor pressure of a solution formed by volatile solute and volatile solvent is as follows
Here vapor pressure of pure cyclohexane is 66.9 torr and vapor pressure of pure toluene is 21.1 torr.
Amount of each component is 124 grams.
We have to find total pressure of the solution
Molar mass of cyclohexane is 84.16 g/mol
Molar mass of toluene is 92.14 g/mol
