Answer 1

Density is the measurement of quantity or mass per unit of volume in a particular substance. Density is mathematically defined as mass divided by volume. Density differs from element to element on the periodic table and is also affected by environmental conditions including temperature and atmospheric pressure.

Answer 2

Density is the mass per unit volume. It can be measured in several ways. The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3.
