Density

Density is a physical property of matter that describes the amount of mass to a unit of volume.

We use the formula below to calculate the density.



 In this formula, D equals M divided by V where D stands for Density, M stands for mass, and V stands for Volume.

Some of the possible units for density are; g/mL, g/L, g/cm³, kg/L

 If an object is less dense than the liquid, it SINKS

 

If an object is more dense than the liquid, it FLOATS

Here's the video showing what happens if you put an egg into two liquids with different density(water&salt water)

 

 

Example Question:

A substance has a mass of 44.1g and a volume of 12.6cm³. What is it's density?

 

Use the formula to calculate the density.

　　　D=M/V

  　　　 =44.1g/12.6cm³

   　　　=3.5g/cm³

So, its density is 3.5g/cm³.

 

 

 

Here's something you can do using different densities the substances have.
