· The density of salt is g/cm³ while the density of sand is g/cm³. In other words, sand is slightly heavier than salt. If you shake a pan of salt and sand, the sand will eventually rise to the top. A similar method is used to pan for gold, since gold has a higher density than most other substances and sinks in a mixture.
