Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What is the relationship between mass and volume in density?

Back

If mass increases while volume stays the same, density increases. If volume increases while mass stays the same, density decreases.
