Calculating Density, Mass, and Volume

What is the formula for calculating density?

• Density = Mass + Volume

• Density = Mass / Volume

• Density = Volume / Mass

• Density = Mass x Volume

What mnemonic can help remember the relationship between density, mass, and volume?

• MDV

• DMV

• VMD

• DVD

If a cake has a mass of 500 grams and a volume of 250 cm^3, what is its density?

• 750 grams/cm^3

• 250 grams/cm^3

• 0.2 grams/cm^3

• 2 grams/cm^3

A block of wood has a mass of 6 grams and a volume of 12 cm^3. What is its density?

• 0.2 grams/cm^3

• 6 grams/cm^3

• 18 grams/cm^3

• 0.5 grams/cm^3

Given a density of 8 grams/cm^3 and a volume of 25 cm^3, what is the mass?

• 8 grams

• 3.125 grams

• 33 grams

• 200 grams

If the density is measured in grams/cm^3 and the volume in cm^3, what is the unit of mass?

• cm^3

• cm

• grams/cm^3

• grams

What happens to the units when calculating mass from density and volume?

• They cancel out

• They remain unchanged

• They are squared

• They are cubed

If a substance's density is known, what else is needed to calculate its mass?

• Its weight

• Its volume

• Its height

• Its area

With a mass of 820 grams and a density of 5 grams/cm^3, what is the volume?

• 164 cm^3

• 4100 cm^3

• 165 cm^3

• 825 cm^3

How do you calculate volume if you know the mass and density?

• Volume = Mass x Density

• Volume = Density / Mass

• Volume = Mass / Density

• Volume = Density + Mass
