Density and Property of Substance Assessment

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find mass using density and volume?

Back

Mass = Density × Volume.

Front

What is the formula to find volume using density and mass?

Back

Volume = Mass / Density.

Front

If a substance has a mass of 100 grams and a volume of 20 cm³, what is its density?

Back

Density = 100 g / 20 cm³ = 5 g/cm³.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.

Front

If an object has a density greater than 1 g/cm³, will it sink or float in water?

Back

It will sink in water.

Front

If an object has a density less than 1 g/cm³, will it sink or float in water?

Back

It will float in water.

Front

What is the density of a block of wood with a mass of 50 grams and a volume of 25 cm³?

Back

Density = 50 g / 25 cm³ = 2 g/cm³.

Front

What is the density of clay with a mass of 150 grams and a volume of 30 cm³?

Back

Density = 150 g / 30 cm³ = 5 g/cm³.
