3. What is Density? Vocabulary – p.31
Mass – The amount of matter in an object.
Volume – The amount of space taken up by some matter.
Density – The mass of a known volume of substance. It is usually measured in g/cm3
Immiscible – A term used to describe liquids that are unable to dissolve in one another.
Miscible – A term used to describe liquids that are able to dissolve in one another.

4. How is density calculated?
Step 1 – Using a triple beam balance, find the mass of your object. Mass is measured in grams.
Step 2 – Use a graduated cylinder if the object is a liquid, a ruler if your object is a regular solid, or water displacement if the object is an irregular solid to find volume. Volume is measured in mL or cm3, depending on it’s state (solid or liquid). 1mL = 1 cm3.
Step 3 – Density is calculated by dividing your mass measurement by your volume measurement or
Density = Mass/Volume.
Density is labeled g/cm3 ,or how much matter is in each cubic cm of an object.
