• It depends on the mass
and the volume of a
material

Depends on:
The type of atom(s)
Copper atoms are
more massive than
aluminum atoms
DensityDensity
How tightly packed
the atoms are
Water molecules are
closer together than
O2 and N2 in the air

Water – 1 g/cm3
Every cm3
weighs
1g
1 cm3
= 1mL
Oil- 0.9 g/cm3
DensityDensity
D = m/V
D = density in g/cm3
m = mass in g
V = volume in cm3
DensityDensity
• Find mass with a
balance or a scale
• Find volume:
• Length x width x height
or
• Water displacement
• A steel block has a mass of 127.82g with a
volume of 16.39 cm3
. What is the density of the
steel block?
