Density, Physical and Chemical Properties

James has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

Which lab tool might you use to measure the volume of a liquid?

• scale
• bunsen burner
• test tube
• graduated cylinder

This is a measurement of the amount of matter, or 'stuff', in an object or substance.

• volume
• density
• mass
• length

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

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = volume/ mass

Which units can be used to express density?

• g/cm^3
• grams
• millimeters
• milliliters

True or False:  The density of a specific type of material never changes.  

• True
• False

If the density of a bar of gold is 19.3 g/cm³and you cut it into 4 pieces,  what is the density of each piece of gold?  

• 4.825 g/cm³
• 9.65 g/cm³
• 19.3 g/cm³
• 38.6 g/cm³

Frank has a paper clip. It has a mass of 9g and a volume of 3cm³. What is its density?

• 3 g/cm³
• 1/3 g/cm³
• 27 g/cm³
• 39 g/cm³

Volume is ...

• Mass/Volume
• The amount of matter in an object.
• The amount of space an object occupies.
• Anything that has mass and occupies space.
