# How to Calculate Density of a Substance?

## What is density and how is it calculated?

Density is the measurement of how much mass is contained in a given volume of a substance. To calculate density, what information do we need?

A. Mass and weight

B. Volume and shape

C. Temperature and pressure

## Answer:

To calculate the density of a substance, you need to know its mass and volume. The formula to calculate density is:

**Density = Mass / Volume**

Density is a fundamental property of matter and is expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). When you know the mass of a substance (in grams or kilograms) and its volume (in cubic centimeters or cubic meters), you can easily calculate its density using the formula mentioned above.

For example, if you have a 1000 g sample of a substance with a volume of 500 cm³, you can calculate its density as follows:

**Density = 1000 g / 500 cm³ = 2 g/cm³**

By finding the ratio of mass to volume, you determine how much mass is present in a unit volume of the substance, which is its density. Understanding how to calculate density is essential in various scientific fields, including chemistry, physics, and engineering.
