Form 1 Chapter 1 Density

Jack 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

If the box has a mass of 72 grams, what is its density?

• 96 g/cm³

• 48 g/cm³

• 24 cm³

• 3 g/cm³

Look at this image.  Which object has the LOWEST density in water? How?

• The Ping Pong Ball because it floats to the top 

• The bolt because it has sunk to the bottom

• The soda cap because it is not just full of air like the Ping Pong ball

What is the formula for density?

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

Why do some substances float on water?

• they are warmer than water
• they are cooler than water
• they are more dense than water
• they are less dense than water

What units are used to measure Density?

• cm³/g
• g
• g/cm³
• cm³

What is the formula for Mass?

• Mass/Volume

• Density x Volume

• Mass/Density

• Density/Mass

• Volume/Mass

What is the formula for Volume?

• Mass/Volume

• Density x Volume

• Mass/Density

• Volume/Mass

• Density/Mass

What is the volume of 55 grams of lead if it has a density of 11 g/cm³?

• 605 cm³

• 5 cm³

• 66 cm³

• .2 cm³

What is the mass of a 100mL liquid if it has a density of 3 g/mL?

• 300 g

• 33.3 g

• .03 g

• 103 mL
