Density and relative density.

1.	Density and relative density.
Answer» Density: It is the mass per unit volume of a body. Density = \(\frac{Mass\,of\,body}{Volume\,of\,body}\) Its SI unit is kg m^-3 Relative density: The relative density of a substance is defined as the ratio of the density of substance to that of water. It is a ratio and thus has no units. Relative Density : \(\frac{Density\,of\,body}{Density\,of\,body}\) It has no unit because it is a ratio.

Answer»

Density: It is the mass per unit volume of a body.

Density = \(\frac{Mass\,of\,body}{Volume\,of\,body}\)

Its SI unit is kg m^-3

Relative density: The relative density of a substance is defined as the ratio of the density of substance to that of water.

It is a ratio and thus has no units.

Relative Density : \(\frac{Density\,of\,body}{Density\,of\,body}\)

It has no unit because it is a ratio.
