*Things to Know*
Solute: The solute is the substance that dissolves. Solvent: is the substance that does the dissolving.
Different Types of Mixtures
Homogenious-- **solutions **suspensions -emulsions -colloidal dispersions
What is A Solution?
a. the process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change. b. such a substance, as dissolved sugar or salt in solution. c. a homogeneous, molecular mixture of two or more substances. (www.dictionary.com)

Saturated Solution?
Saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of it will appear as a precipitate. ... (www.wikepedia.com)
How to identify different types of mixtures? By expirementing you can find the difference of it.. For example, for saturated sollution, mixing sugar and water until the water won't take anymore sugar.
Solute divided by Solvent 5 sugar divided by 25 water = 33% or1 Concentration may be expressed several different ways, using percent composition by mass, mole fraction, molarity, molality, or normality. Calculating Concentration Concentration Units & Dilutions By Anne Marie Helmenstine, Ph.D., Percent Composition by Mass (%) This is the mass of the solute divided by the mass of the solution (mass of solute plus mass of solvent), multiplied by 100. Example: Determine the percent composition by mass of a 100 g salt solution which contains 20 g salt. Solution: 20 g NaCl / 100 g solution x 100 = 20% NaCl solution
