What does density have to do with atoms?
Density describes how atoms float.
Density describes how closely the atoms of an object are packed together.
Density describes how many atoms an object has.
Density! Atoms! They have NOTHING to do with each other!
If the mass of an unknown substance is 56.0 g and the volume is 7.0 cm3.
What would be its density? HINT: Density = Mass/Volume
Example: 55.0 g/5.0 cm3 = 11.0 g/cm3
8.0 g/cm3
0.13 g/cm3
49.0 g/cm3
63.0 g/cm3
Mass of Object = 72 g
Volume of Object = 36 cm3
What would be its density? HINT: Density = Mass/Volume
Example: 32.0 g/4.0 cm3 = 8.0 g/cm3
108 g/cm3
0.5 g/cm3
36.0 g/cm3
2.0 g/cm3
Calculate the density of the cube.
HINT: Volume = L x W x H
Example: 5 x 2 x 3 = 30 cm3
HINT: Density = Mass/Volume
Example: 240 g/30 cm3 = 8 g/cm3
2.0 g/cm3
4.0 g/cm3
6.0 g/cm3
8.0 g/cm3
