How to calculate density

In this section let me help you on how to calculate density
Introduction to calculate density


Density of substance is defined as the ratio of the mass of a body to its volume.
This is given by ρ = m/v. Here, ρ denotes the density of the substance; m denotes the mass of the substance and v denotes the volume of the substance. Let us do some problems to calculate density of some substances now.

Problems to Calculate Density -

Example: The density of a liquid is 2 kg/cm3. The volume of the liquid is 44 cm3. What is the mass of the liquid? This will also help us in additive inverse property

Solution: Given: v = 44 cm3, ρ = 2 kg/cm3.
Mass, m = ρ × v

= 2 × 44

= 88 kg.
