What is the relationship between solution amount and molarity

A solution is a homogeneous mixture composed of two or more substances.  The substances can be solids, liquids, or gasses. The substance that makes up most of the solution is called the solvent.  If the solvent is water, then the solution is called an aqueous solution.  The minor components of the solution are called solutes.  For example, if we dissolve 2 grams of sugar and 4 grams of salt in 2 L of water, water is the solvent while sugar and salt are solutes.  This would be an example of an aqueous solution.  Since living organisms are composed mostly of water, studying the chemistry of life largely involves studying the chemistry of aqueous solutions.  Therefore, preparing aqueous solutions is an essential skill in molecular and cellular biology labs. A third way to describe the concentration of a solution is by molarity.  With molarity, the amount of solute present is measured in units called moles rather than grams or milliliters.  How much is a mole?  One mole (1 mol) of any

Because a model would make the investigation easier to understand
