Density

Density is a measure of how much mass is contained in a given volume. It is a property of matter that describes the compactness of a substance. The formula for calculating density is:

Density = Mass / Volume

Where:

• Density is measured in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L).
• Mass is the amount of matter in an object and is measured in units such as grams (g) or kilograms (kg).
• Volume is the amount of space an object occupies and is measured in units such as cubic centimeters (cm³) or liters (L).

Example

If a substance has a mass of 50 grams and a volume of 10 cubic centimeters, its density would be:

Density = 50g / 10cm³ = 5g/cm³
