Abstract
We have shown that when two things are mixed together we can calculate the entropy of mixing. We can also calculate the concentration of this mixture, as we did in the previous three examples. A most complete description of the chemicals and their mixtures is by using Gibbs free energy (we say it is free because it does not contain any pV work, like when we are working with gases). Let us think for a moment of the following mixture: a solution of urea, O=C(NH2)2, in water, H2O. Water, a liquid, is present in larger quantity so we call it the solvent.
