Density (MIDTERM Review)

Calculate the density of the cube.

• 2 g/cm³

• 4 g/cm³

• 6 g/cm³

• 8 g/cm³

What is the formula for calculating density?

• Density = Mass × Volume

• Density = Mass ÷ Volume

• Density = Volume ÷ Mass

• Density = Mass + Volume

If an object has a mass of 50 grams and a volume of 10 cubic centimeters, what is its density?

• 5 g/cm³

• 0.2 g/cm³

• 500 g/cm³

• 60 g/cm³

Which of the following units is commonly used to express density?

• grams (g)

• cubic meters (m³)

• grams per cubic centimeter (g/cm³)

• liters (L)

A block of wood has a density of 0.6 g/cm³. If its volume is 20 cm³, what is its mass?

• 12 grams

• 30 grams

• 0.03 grams

• 33.3 grams

If the density of water is 1 g/cm³, which of the following objects will float on water?

• An object with a density of 1.2 g/cm³

• An object with a density of 0.8 g/cm³

• An object with a density of 1 g/cm³

• An object with a density of 2 g/cm³

A metal cube has a side length of 2 cm and a mass of 32 grams. What is its density?

• 4 g/cm³

• 8 g/cm³

• 16 g/cm³

• 2 g/cm³

If two objects have the same volume but different masses, which one has a higher density?

• The one with the larger mass

• The one with the smaller mass

• They have the same density

• Density cannot be determined from mass and volume

A liquid has a mass of 250 grams and occupies a volume of 500 mL. What is its density in g/mL?

• 0.5 g/mL

• 2 g/mL

• 1 g/mL

• 0.25 g/mL
