5) Concentration of solutions

• The concentration of a solution is often measured using units of mol/dm3
• concentration of a solution = amount of substance (mol) /volume (dm3)
•  If 1.00 mole of solute is dissolved to form a solution that has a volume of 1.00dm3, the solution has a concentration of 1.00mol/dm3.
• Occasionally concentrations are expressed in g/dm3.

  If 10.0g solute is dissolved to form a solution that has a volume of 1.00dm3, the solution has a concentration of 10.0g/dm3.
