Depends on these two properties:

• MASS: MASS: amount amount of matter you of matter you are made ofare made of

• VOLUME: VOLUME: amount of amount of space space something something takes uptakes up

• Volume is the amount of space that something takes up.

• To find the volume of a solid cube or rectangle, you measure the length, width, and height of the object and multiply them together.

Density

A measure of the amount of A measure of the amount of mattermatter that occupies a given amount of that occupies a given amount of spacespace

SPACE

Amount of Matter

• Solid objects, liquids and gases are made up of atoms and molecules so they have both mass and volume.

• The density of a material is The density of a material is always the same under the always the same under the same conditionssame conditions!!!!!!

• Density can be used to identify materials.

How does the density of a steel cube compare to the density of a nail?

Units for DensityUnits for Density =

Grams per cubic centimeter

g/cm3

A piece of tin has a mass of 16.52 g and a volume of 2.26 cm3. What is the density of tin?

What is the mass of an object that has a density of 8 g/cm3 and a volume of 64 cm3?

What is the volume of 325 g of a metal with a density of 9.0 g/cm3?

Well…there are a known set of densities on record throughout the world

1.0 g/cm3

An object’s ability to float in water

Density Greater than 1.0 g/cm3 =

Density Less than 1.0 g/cm3 =

You can calculate the density from a mass vs. volume graph: it is the SLOPE of the line!
