A substance’s density is the measure of the mass of material within a certain volume. (amnt of space taken up)

The mass (amount of particles) is affected by how tightly packed the molecules are within the space.

Same Volume/Diff Mass

A B

A and B = SAME VOLUME (same size)

A B

A and B = SAME VOLUME (same size)

A B

A and B = DIFFERENT MASS (amount of particles; different substance)

Different Densities

C D

C and D = DIFFERENT VOLUME (different size) but same substance

C D

C and D = DIFFERENT VOLUME (different size) but same substance

Same Densities-

particles are packed the

same way

1. VOLUME – amount of space• mL, cm3, cc

2. MASS – amount of particles Any gram unit

3. DENSITY – how the particles are packed- RATIO• g/mL , g/cm3, g/cc, kg/m3

Combination Units
