Molarity, Molality, Dilutions, Percent Solutions, & Mole Fractions
Dilutions and Percent Solutions
Taking a concentrated solution and making it less concentrated.
Examples-Molarity and Dilutions. Example What is the molarity of a solution that contains 4.5 moles of sucrose in L of water?
Solution Concentration. Review A solution is a homogeneous mixture. The solvent is the major component of the solution. The solute is the minor.

Solution Concentration Section 14.2 Concentration - amount of solute dissolved in a specific amount of solvent concentrated - a lot of solute dilute.
Preparing a Molar Solution
DETERMING CONCENTRATIONS OF SOLUTIONS. MOLAR Molar is mol solube/1 L solution Making molar solution 1)Add ½ of the total solvent 2)Add required amount.
