Final answer:
The given information about the metal's weight in different mediums can be used to determine its relative density.
Step-by-step explanation:
The given information about the metal's weight in different mediums can be used to determine its relative density. Relative density is the ratio of the density of a substance to the density of a reference substance, usually water. Since the metal weighs less in water and gasoline compared to air, it means that the metal has a lower relative density in water and gasoline.
