Mass is a physical property of an object. It is a measure of the quantity of a substance. It is a positive scalar. Mass is divided into inertial mass and gravitational mass. Any substance in nature has both an inertial mass and a gravitational mass. The "matter" mentioned here is a general term for macroscopic objects and electromagnetic fields, celestial bodies and galaxies, and basic particles in the microworld in nature.

Density calculation formula: density = mass / volume ( = m / V ) (mass and
In the laboratory,
Calculating
