Molarity 1

  1. 1. MOLARITY
  2. 2. MOLARITY A unit on concentration that is the ratio between moles of DISSOLVED substance and liters of solution
  3. 3. Molarity (M) = moles of solute (mol) volume of solution (L)
  4. 4. There are many ways to represent molarity: <ul><li>Molarity </li></ul><ul><li>M </li></ul><ul><li>Molar </li></ul><ul><li>mol / L </li></ul>
  5. 5. MAKE SURE YOUR UNITS ARE CORRECT!!! ALWAYS mol/L
  6. 6. Homogeneous Mixtures are also known as SOLUTIONS! !
  7. 7. Solutions are made up of two parts <ul><li>Solute </li></ul><ul><li>Solvent </li></ul>
  8. 8. SOLUTE the part of a solution present in the LEAST amount (what is dissolved)
  9. 9. SOLVENT the part of a solution present in the greatest amount (what does the dissolving)
  10. 10. SOLUTION!!! = Solvent Solute
  11. 11. Solubility amount of solute that will dissolve in an amount of solvent at a given temperature
  12. 12. Saturated Solution contains the maximum amount of solute for an amount of solvent at a given temperature
  13. 13. Unsaturated Solution contains less solute than a saturated solution
  14. 14. Supersaturated Solution contains more solute than it should theoretically be able to hold at a certain temp
  15. 15. MOLARITY A measurement of concentration of a solution
  16. 16. MOLARITY moles of solute divided by liters of solution
  17. 17. MOLARITY
  18. 18. Colligative Property property of a solution that depends only on the concentration of the solution
  19. 19. Two Main Colligative Properties: <ul><li>Boiling Point Elevation </li></ul><ul><li>(Ex: Antifreeze in cars) </li></ul><ul><li>Freezing Point Depression </li></ul><ul><li>(Ex: Salt on icy roads) </li></ul>
