    Molarity 1 Molarity 1 Presentation Transcript

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