Density means mass per unit volume

Density = mass / volume

Particles in solids are very closely packed so they have high density. In gases, there is plenty of spaces between particles due to which density is low.

S.I unit of density is kgm– 3 (kilogram per cubic meter).

Answer 2

Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.

Each substance has a specific density. Generally, the density of water (which is approximately about 1 gram/cubic centimeter) is taken as the standard value for calculating the density of substances. However, the SI unit of Density is measured using kilograms per cubic meter (kg/m3).
