Question

What Is Relative Density . What it's use for. and Formula For Relative Density​

Answer 1

Answer:

If the reference material is water, then a substance with a relative density (or specific gravity) less than 1 will float in water. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink.

Answer 2

Answer:

The relative density is the ratio of the mass of the suubstance in air at 20 degree Celsius to that of an equal volume of water at the same temperature.

Relative density can also help to quantify the buoyancy of a substance in a fluid or gas, or determine the density of an unknown substance from the known density of another. Relative density is often used by geologist and mineralologist to help determine the mineral content of a rock or other sample.

formula- RD= substance/ reference.
