CONCENTRATION OF SOLUTION
www.citycollegiate.com
   Concentration of solution is defined as the amount of solute dissolved in a specific (fixed) amount of    solvent.

UNITS OF CONCENTRATION

   Molarity
   Molality
   Normality
   Percentage composition
   Mole fraction
MOLARITY
Molarity is defined as the number of moles of solute dissolved in one litre (one dm3) of solution.
   For example:
   If 2 moles of a solute are present in one litre of a solution then the molarity of solution will be (2M).
FORMULA
www.citycollegiate.com
Molarity = number of moles of solute /volume of solution in litre
OR
Molarity = mass of solute (in grams) /molecular mass x volume of solution in litre
PERCENTAGE OF COMPOSITION OF SOLUTION
   Concentration of a solution can be expressed in terms of percentage composition. It is based on the             weight or volume of the components of solution.
Weight / Weight %
   2% w / w solution means grams of solute is dissolved in 100 grams of solution.
Weight / volume %
   4% w / v solution means 4 grams of solute is dissolved in 100 ml of solution.
Volume / weight %
   3% v/ w solution means 3 ml of solute is dissolved in 100 grams of solution.
Volume / volume %

   5% v / v solution means 5 ml of solute is dissolved 100 ml of solution.
