Density Formula
Density is a physical property of matter that describes how compact or dense a substance is. It is defined as the mass of a substance per unit volume. The formula for density is:

Density = Mass / Volume

Explanation
- Mass: Mass refers to the amount of matter in an object. It is typically measured in grams (g) or kilograms (kg).
- Volume: Volume is the amount of space that an object occupies. It is usually measured in cubic centimeters (cm³) or cubic meters (m³).
- To calculate the density of an object, you need to know both the mass and volume of the object. Once you have these values, you can simply divide the mass by the volume to determine the density.

Example
For example, if you have a block of metal with a mass of 100 grams and a volume of 50 cm³, you can calculate the density as follows:
Density = 100 g / 50 cm³ = 2 g/cm³
This means that the density of the metal block is 2 grams per cubic centimeter.

Importance
Density is an important property in various scientific fields, including physics, chemistry, and engineering. It can help identify substances, determine the purity of materials, and predict how objects will interact with each other. Understanding density is crucial for many practical applications, such as designing materials, conducting experiments, and analyzing the composition of substances.
