Density Formula

Density is all about the compactness in molecular arrangement  in any substance which decides how heavier or lighter any substance is.

Density is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities. Density is defined as mass per unit volume.

Let us Consider ice cubes on the water we could see ice floats on water which tells us that water is denser than ice.

Density is calculated using the below formula. It is represented by $\rho$.

Weight Density formula is given by,

The Density is expressed in Kg/L. The Density Formula is used to determine the density of any given body.

Density Problems

Problems based on density are mentioned below:

Solved Examples

Question 1: Find the density of water if it has mass of 1000 Kg and Volume of 1m3?
Solution:

Density is given by formula $\rho$ = $\frac{Mass}{Volume}$
= $\frac{1000 Kg}{1 m^{3}}$
= 1000 Kg/m3.

Question 2: Find the Volume of the container if it can hold 150 Kg of oil having density of 890 Kg/m3?
Solution:

Given: Mass m = 150 Kg,
Density $\rho$ = 890 Kg/m3,
Volume V = $\frac{m}{\rho}$
= $\frac{150 Kg}{890 Kg/m^{3}}$
= 0.168 m3.
