Concentration: Quantitive Chemistry: Chemistry: GCSE (9:1)

• Concentration

  A measurement of how much solute exists within a certain volume of solvent
• Concentrated solution

  large amount of solute

  
• Dilute solution


  small amount of solute

  
• Solvent


  A substance capable of dissolving other substances

  
• Solute


  Substance being dissolved

  
• Formula of concentration in mol/dm3

  moles (mol) / vol (dm3)

  
• Formula of concentration in g/dm3

  mass (g) / vol (dm3)

  
• 1 dm3 in cm3

  1000 cm3

  
• 1 cm3 in dm3

  0.001 dm3

  
• Converting g/dm3 to mol/dm3

  Concentration (g/dm3) / Mr
• Converting mol/dm3 to g/dm3

  Concentration (mol/dm3) x Mr
• Ways to increase concentration of a solution

  Add more solute, evaporate solvent
• Ways to decrease concentration of a solution

  Add more solvent
