solution. The terms concentrated and dilute are just relative expressions. A concentrated solution has more solute in it than a dilute solution; however, this does not give any indication of the exact amount of solute present. Therefore, we need more exact, quantitative methods of expressing concentration.
2. Concentration Units The following are the six methods to calculate the concentration of a solution: 1. Percent by Mass 2. Percent by Volume 3. Molarity or Molar Concentration (M) 4. Molality or Molal Concentration (m) 5. Mole Fraction (X) 6. Normality
