  1. Density Density is the mass per unit volume of an object

  2. Density = mass D = m Volume V Density = love • Mass and volume are extensive properties. These values change depending on how much material you have. • Density is an intensive property. It does not change according to how much you have.

  3. Volume can be measure by Length x width x height or the Water Displacement method • Materials of lower density will float on materials of greater density. Density of water is 1.0 g/cm3 1mL = 1cm3 The appropriate units of density are: • g/cm3for solids • g/mLfor liquids

  4. Graphing density • If you have various masses and volumes of an object you can graph your data and solve for the slope to find the density of that object. Slope = Δy or y2 – y1 Δx x2 – x1

  5. Find the Density of Copper

  6. Graph • Plot X vs Y graph

  7. Calculating density Ex. 1) A piece of beeswax with a volume of 8.50cm3 is found to have a mass of 8.060g. What is the density of the beeswax? Will it float or sink in a beaker full of H2O?

  8. Ex. 2) A sample of magnesium has a volume of 825.00 cm3 and a density of 1.74 g/cm3, what is the mass of Mg?

  9. Ex. 3) The volume of water in a graduated cylinder is 27.0 mL. A piece of lead is slowly dropped into the cylinder giving the volume to become 130.2 mL. Given that lead’s density is 11.3g/cm3 what is the mass of Pb?

  10. Ex. 4) An empty beaker has a mass of 25.83g. When it is filled with mercury, it’s new mass is 225.3g. If the density of mercury is 13.60 g/cm3, what is the volume of the beaker?
