Density Practice

Which is more dense?

• Left

• Right

• Both have the same density

A sample of liquid mercury has a mass of 76.2g and has a volume of 5.60 mL. What is its density?

• 13.6 g/mL

• 426.72 g/mL

• 81.8 g/mL

• 70.6 g g/mL

Volume = 20 ml

Mass = 100 g

Density = ?

• 50 g/ml

• 5 g

• 5 g/ml

• 5 ml/g

Mass = ?

Volume = 3 ml

Density =7 g/ml

(a)  

• 21g
• 4g
• 2.3g
• 0.43g

Volume = 45 ml

Mass = 247.5 g

Density = ?

• 5.5 g/ml

• 0.2 g/ml

• 5.5 ml

• 202.5 g/ml

Mass = 21g

Volume = 3 ml

Density =?

• 3 g/ml

• 7 g/ml

• 21 g/ml

• 0 g/ml

Based only on what you can observe in the picture, which statement is true?

• Substance #2 is less dense than substance #3.

• Substance #1 is the most dense.

• Substance #3 is more dense than substance #4.

• Substance #4 is less dense than substance #1.

Place the substances in order of most dense. (put MOST dense as #1)

• Corn Oil

• Glycerin

• Water

• Corn Syrup 

An apple displaced 10mL of water, the volume of the apple is 

• 25 mL
• 5 mL
• 10 mL
• 0 mL

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
