Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find mass if density and volume are known?

Back

Mass = Density × Volume.

Front

What is the formula to find volume if density and mass are known?

Back

Volume = Mass / Density.

What is the density of water?

Back

The density of water is approximately 1 g/mL.

Front

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

Back

Density = 50 g / 10 mL = 5 g/mL.

What is the density of aluminum?

Back

The density of aluminum is approximately 2.7 g/cm³.

Front

If a rock has a mass of 21 grams and a volume of 3 cm³, what is its density?

Back

Density = 21 g / 3 cm³ = 7 g/cm³.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density increases.
