In Dilutions, a solvent (usually water) is added to a concentrated solution. 

Concentrated & Diluted Solutions

Concept #1: Dilutions

Example #1: If each sphere represents a mole of solute from the images provided below, arrange the solutions from least concentrated to most concentrated.

Concept #2: Dilution Calculations

Example #2: What volume (in mL) of 5.2 M HBr must be used to prepare 3.5 L of 2.7 M HBr?

Practice: To what final volume would 100 mL of 5.0 M KCl have to be diluted in order to make a solution that is 0.54 M KCl?

Practice: If 880 mL of water is added to 125.0 mL of a 0.770 M HBrO4 solution what is the resulting molarity?

Practice: A student prepared a stock solution by dissolving 25.00 g of NaOH in enough water to make 150.0 mL solution. The student took 20.0 mL of the stock solution and diluted it with enough water to make 250.0 mL solution. Finally taking 75.0 mL of that solution and dissolving it in water to make 500 mL solution. What is the concentration of NaOH for this final solution? (MW of NaOH: 40.00 g/mol).
