Density

The density of an object is it's mass divided by it's volume.

d= m/v
m=d*v
v=m/d

d=Density
m=Mass
v= Volume





(*note: unit^3  means the Si unit is cube for example meters cube(m^3)

It is usually expressed in Kg/l, Kg/m^3, or g/cm^3.
kg or g would be SI units for m (mass)
l, m^3, or cm^3 would be SI units for v (volume)

Mass is a measurement of the quantity of matter. Matter is continually the same no matter what.
Some important liquids to remember are:

Examples of how to find a density:
What is the density of an object that has a mass of 160g and a volume of 35cm^3?
d=m/v
d=160g/32cm^3
d=5 g/cm^3


Example of how to find volume
If an object has a density of 0.7g/cm^3 and a matter of 124g, what is the volume?
v= m*d
v= 0.7 x 124
v=86.80cm^3
