mass=35.64 g
volumes = 3.39 ml
use
Density = mass/volume
but I think you can see which metal it is with out calculating the density.
A student finds a medallion which could be made of pure platinium or silver. IN order to find out what the medallion is made of the student takes the medallion to a chemistry lab. The student measures the density of the medallion as follows. The medallion is placed on a balance and the mass is found to be 35.64g. The student places some water in a graduated cylinder and reads the volume as 65.5mL. Next, the medallion is dropped into the cylinder and the new volume reads 68.89mL. Is the Medallion platinum or Silver? (densities: platinum= 21.4g/mL Silver= 10.5g/mL
