Density Review

D = m/v mass divided by volume NOT volume divided by mass

units of density when measuring liquids
**g/ml **

units of density when measuring solids
**g/cm ^{3}
**

density of water:
1.0 **g/ml
**because it floats on water

density of oil:
< 1.0 **g/ml **

density of copper penny
> 1.0 **g/ml **
because it sinks in water
