Definition of Density and its Formula

Density can be defined as the measure of how much mass is contained within a given volume of a substance. It is commonly represented by the symbol “ρ” (rho) and is calculated by dividing the mass of an object by its volume. The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

The unit of measurement for density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). It is important to note that density is an intensive property, meaning it does not depend on the size or amount of the material being measured.

Calculation of Density

To calculate the density of a material, you need to know its mass and volume. The mass can be determined using a balance or scale, while the volume can be measured using various techniques such as displacement or geometric calculations.

For example, if you have a solid object with a mass of 100 grams and a volume of 50 cubic centimeters, you can calculate its density as follows:

Density (ρ) = 100 g / 50 cm³ = 2 g/cm³

Similarly, if you have a liquid with a mass of 500 grams and a volume of 250 milliliters, you can calculate its density as:

Density (ρ) = 500 g / 250 mL = 2 g/mL
