Solution Chemistry
Most of the "chemistry" that we experience involves one or more substances dissolved in another. For example, the chemical reactions that occur in your body involve the interaction of compounds that are dissolved in your blood and other bodily fluids - all of which are based on water as the primary medium. These solution are called "aqueous" solutions from the Latin word "aqua" meaning "water."
Molarity and Solution Concentration
When a certain amount of a substance (called the solute) measured in moles is dissolved in another substance (called the solvent) we can speak of the concentration of the solute in terms of "moles of solute / liters of solution" or molarity abbreviated mol/L or M.
Required Reading: Calculations in Chemistry, Lesson 10.3 - 10.6, p. 202 - 217.
Optional Reading: General Chemistry, "Working with Solutions" - Molar Concentrations, Chapter 4.7, p. 156 - 158.

Dilution
We often need to make a solution that is less concentrated (i.e. has less quantity of solute per volume of solution) than the solution concentration that we have on hand. This process is called dilution.

Optional Reading: General Chemistry, Chapter 4.8, p. 158 - 160.
