Density

Front

What is density?

Back

Density is the mass of an object 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

What is population density?

Back

Population density is a measurement of the number of people living per unit area, often expressed as people per square mile or square kilometer.

Front

If a box has a mass of 200 g and a volume of 50 mL, what is its density?

Back

Density = 200 g / 50 mL = 4 g/mL.

Front

What is the density of water?

Back

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

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because it expands.

Front

What is the relationship between density and buoyancy?

Back

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

Front

What is the density of a material with a mass of 100 g and a volume of 25 cm³?

Back

Density = 100 g / 25 cm³ = 4 g/cm³.
