Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically 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 the volume of a liquid if you know its mass and density?

Back

Volume = Mass / Density.

Front

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

Back

It will float.

Front

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

Back

It will sink.

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL.

Front

Calculate the density of an object with a mass of 10 g and a volume of 5 cm³.

Back

Density = 10 g / 5 cm³ = 2 g/cm³.

Front

What is the mass of a liquid with a volume of 50 mL and a density of 2 g/mL?

Back

Mass = Volume x Density = 50 mL x 2 g/mL = 100 g.

Front

What is the volume of a substance with a mass of 30 g and a density of 6 g/mL?

Back

Volume = Mass / Density = 30 g / 6 g/mL = 5 mL.

Front

If a rock has a mass of 20 g and a volume of 4 cm³, what is its density?

Back

Density = 20 g / 4 cm³ = 5 g/cm³.
