KG_Density & Metals, Non-Metals, Metalloids

Density is...

• the amount of mass in an object
• the amount of space an object takes up
• the amount of mass in a given space
• the weight of an object

Density is calculated by dividing the mass of a substance by its -

• volume
• weight
• length
• temperature
