Molarity (video) | Solutions and mixtures | Khan Academy
The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution.
How to calculate molarity (article) | Khan Academy
You can mix a smaller amount of a liquid into a larger amount of another liquid and use molarity where the minor liquid is the solute and the major liquid is the solvent.
