Density Review

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 unit of density for liquids?

Back

The unit of density for liquids is typically grams per milliliter (g/mL).

Front

What is the unit of density for solids?

Back

The unit of density for solids is typically grams per cubic centimeter (g/cm³).

Front

If an object has a mass of 100 g and a volume of 50 mL, what is its density?

Back

Density = 100 g / 50 mL = 2 g/mL.

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL at 4°C.

Front

How can you determine if an object will float or sink in water?

Back

An object will float if its density is less than that of water (1 g/mL) and sink if its density is greater.
