Question
Chapter 4.3, Problem 8E
Interpretation Introduction
Interpretation:Among water, methanol and ethanol, compound that has the highest and lowest boiling point should be determined.
Concept introduction:Vapor pressure is known as pressure of vapor that exists in equilibrium with its liquid or solid state. In other words, it is equilibrium pressure of vapor over its liquid or solid state. It depends on temperature of system.

The normal boiling point of cyclohexane is 81 °C. What's the vapor pressure of cyclohexane at 81 °C?
At 20.0 °C, the vapor pressure of cyclohexane, a nonpolar hydrocarbon, is 66.9 torr and that of toluene, a hydrocarbon related to
benzene, is 21.1 torr. Calculate the expected vapor pressure of a mixture of cyclohexane and toluene that consists of 124 grams of
each liquid.
