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.

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!
