Mass, volume and density

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams (g) or kilograms (kg).

Front

What is volume?

Back

Volume is the amount of space that a substance or object occupies, usually measured in liters (L) or milliliters (mL).

Front

What is density?

Back

Density is the mass of a substance divided by its volume, commonly expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula for calculating mass?

Back

Mass = Density x Volume.

Front

What is the formula for calculating volume?

Back

Volume = Mass / Density.

Front

If a liquid has a density of 2 g/mL, what is the mass of 50 mL of this liquid?

Back

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

Front

Why do helium balloons rise in air?

Back

Helium balloons rise because helium is less dense than air.

Front

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

Back

The density of the object increases.

Front

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

Back

The density of the object decreases.
