Measuring Density

How can we measure density?

Mass is the amount of matter in a
substance (# of particles).

Volume is a measurement of the
amount of space occupied by a
substance (space the particles take up).

How to measure…

VOLUME:

liquids - graduated
cylinder (mL)

solids - measure water
displacement (DEMO) or
V = l x w x h

(cm3)

VOLUME is measured in
mL for liquids
cm3 for solids

Open Ended

You are needing to measure the volume of a pencil.
1. Explain how you could use water displacement to calculate the volume
2. Share whether the volume units would be mL or cm³

How to measure…

MASS:

triple beam scale

MASS is measured in
grams (g)

Density Calculation Example

What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 50 cm3?

Density = mass ÷ volume

Density = 25 grams ÷ 50 cm3

Density = 0.5 g/cm3

The density of the piece of wood is 0.5 grams every cubic centimeter.

Multiple Choice

A cup of gold colored metal beads was measured to have a mass 425 grams.
By water displacement, the volume of the beads was calculated to be 48.0 cm3.
Given the following densities, identify the metal. Did you strike gold?

• Gold: 19.3 g/mL

• Copper: 8.86 g/mL

• Bronze: 9.87 g/mL
