Another mixture of decane and diethyl ether is used to demonstrate Raoult's Law. Students are asked to predict the vapor pressure of the mixture.
The measurement of pressure exerted by a vapor is demonstrated using barometers. Vapor pressure varies with the strength of the intermolecular forces in the liquid.
In this section we will look at vapor pressure of mixtures. We can calculate the vapor pressure of a mixture using Raoult's law.
Here we wil consider a solution that contains 0.3 mole fraction of decane and 0.7 mole fraction of diethyl ether.
