A bar of copper has a mass of 216g and a volume of 24 cm3. What is the density of copper?

• 9g/cm3

• 5184g/cm3

• .11g/cm3

• 322mL

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

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

Helium balloons rise on earth because

• helium is less dense than air
• helium is more dense than air
• helium is cooler than air
• helium is warmer than air

Using the picture, tell me which object is the least dense and why?

• The fish because he is in the middle

• The cork because it is floating at the top of the water

• The rock because it is at the bottom

• The cork and the rock because they have the same about of atoms.

An irregularly shaped piece of gold was lowered into a graduated cylinder holding a volume of water equal to 17 ml. The height of the water rose to 20 ml. If the mass of the gold was 27 g, what was its density?

• 9 g/mL
• 10.5 g/mL
• 6.5 g/mL
• 8 g/mL
