INTERACTIVE EXAMPLE Determining Density At a local pawn shop a student finds a medallion that the shop owner insists is pure platinum. However, the student suspects that the medallion may actually be silver or aluminum, which are much less valuable. The student buys the medallion only after the shop owner agrees to refund the price if the medallion is returned within two days. Th student, a chemistry major, then takes the medallion to her lab and measures its density as follows. She first weighs the medallion and finds its mass to be 55.64 g. She then places some water in a graduated cylinder and reads the volume as 75.2 mL. Next she drops the medallion into the cylinder and reads the new volume as 77.8 mL. Is the medallion platinum (density = 21.4 g/cm3), silver (density = 10.5 g/cm³), or aluminum (density = 2.70 g/cm³)? HOW DO WE GET THERE? Determine the density of the medallion.

![INTERACTIVE EXAMPLE Determining Density
At a local pawn shop a student finds a medallion that the shop owner insists is pure platinum. However, the student suspects that the medallion may actually be silver or
aluminum, which are much less valuable. The student buys the medallion only after the shop owner agrees to refund the price if the medallion is returned within two days. The
student, a chemistry major, then takes the medallion to her lab and measures its density as follows. She first weighs the medallion and finds its mass to be 55.64 g. She then
places some water in a graduated cylinder and reads the volume as 75.2 mL. Next she drops the medallion into the cylinder and reads the new volume as 77.8 mL. Is the
medallion platinum (density = 21.4 g/cm3), silver (density = 10.5 g/cm³), or aluminum (density = 2.70 g/cm³)?
