  Intensive and Extensive Properties
• 2.
  Extensive - Properties thatdo depend on the amount of matter present. Mass, weight, volume, length
• 3.
  Intensive Properties that donot depend on the amount of the matter present. Color , odor, hardness, melting/freezing point, boiling point, density, malleability, luster

  Density Density = 135g = 2.70 g/mL 50 mL Density = mass (g) volume (mL) Volume can either be determined by the water displacement method or V = L x W x H (units will be cubic centimeters cm3 ) Example: Calculate the density in g/mL of aluminum if a 50 mL block weighs 135 g Solution: Apply the definition:
