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
