What is density? Well density is the amount per unit size. Density is a physical property of matterYou can use density in everyday life, like swimming for example.
Density= Mass/Volume <-- This formula is interchangeable, we can also use this formula to find the mass and or volume.
For a solid the units for density would be g/cm3.
For a liquid the units for density would be g/mL.
Example.
Volumer=Mass/Density and Mass=(Density)(Volume)
**Remember, if the density of an object is greater than the density of the liquid, it would sink. If the density of an object is lesser than the density of the liquid, it would float.
Watch this! Good song on how to remember the density formula!
