Calculating Density

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).

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.

Front

If a substance has a mass of 100 g and a volume of 50 cm³, what is its density?

Back

Density = 100 g / 50 cm³ = 2 g/cm³.

Front

What happens to the density of a substance if its mass increases while its volume remains constant?

Back

The density increases.

Front

What happens to the density of a substance 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/cm³.

Front

How can you determine the density of an irregularly shaped object?

Back

By measuring its mass and the volume of water it displaces when submerged.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid it is in.
