Density and Mass Review

The rock has a mass of 115 g and a density of 30 g/cm³. What is the volume of the rock?

An irregularly shaped rock has a volume of 50 ml. The mass of the rock is 225 g. What is the density of the rock?

Will the rock float on water? The density of water is 1.0 g/mL.

• Yes, the rock will float on water.

• No, the rock will not float on water.

A soccer ball has a volume of 23.5 cm³ and a density of 65.7 g/cm³. What is the mass of the soccer ball?

Find the volume if a substance has a density of 19.3g/cm3 and a mass of 10g.

• .52cm3

• 193cm3

• 1.93cm3

• 29.3cm3

Volume is __________.

• how many atoms
• how much matter is in an object
• how  much something weighs
• how much space an object takes up

What is the formula for density?

• density = mass x volume
• density = mass ÷ volume 
• density = mass + volume
• density = mass - volume

What is the formula for Volume?

• Mass/Volume

• Density x Volume

• Mass/Density

1. Which has a greater density? A piece of wood that has a mass of 15 g or a piece of the same wood that has a mass of 10 g.  Each piece of wood is made of identical (same) material.  

• The piece of wood that has a mass of 15 g.

• The piece of wood that has a mass of 10 g.

• Both have the same density
