What two types of measurements make up DENSITY? 

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

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

Why do the liquids form different layers?

• They have different densities.  
• They have different masses.  
• They have different volumes.  
• They are different temperatures.  

What units can be used to express density?

• density
• volume
• mass
• matter
