Density

What is density?
Density is a physical property of matter. The formula to find density is:

Density = mass / volume

Ways you can tell how dense an object is through weight and sight suggested in these pictures:

-If the density of an object is greater than that of water the object will sink.

-If the density of an object is lower than that of water the object will float.

an example of how to find the density of an iron bar:
1200 g / 1.25 L = 960 g / L
