The quantity of mass of a substance per unit volume is known as density. Density of a substance can be calculated by taking ratio of mass to volume. The symbol which is used to represent density is ρ.
ρ= m/ V
ρ= density of the substance
m = mass
V= volume
The standard international unit for density is kilogram per meter cube. Density of a substance can be calculated in kilogram per litter and grams per milliliter. According to the ideal gas equation, the density of an ideal gas is;
ρ= MP/RT
M= molar mass
P = pressure
R = ideal gas constant
T= temperature
If a substance is incompressible, then its density is constant.
ρ= m/ V
