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 an object occupies, usually measured in milliliters (mL) or cubic centimeters (cm³).

Front

What is density?

Back

Density is the mass of an object divided by its volume, expressed as D = M / V, typically measured in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density is calculated using the formula: D = M / V, where D is density, M is mass, and V is 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 cm³, what is its density?

Back

Density = Mass / Volume = 100 g / 50 cm³ = 2 g/cm³.

Front

What happens to the water level in a graduated cylinder when an object is submerged?

Back

The water level rises by the volume of the object submerged, according to Archimedes' principle.

Front

If 50 mL of water is in a graduated cylinder and an object is added causing the level to rise to 60 mL, what is the volume of the object?

Back

The volume of the object is 10 mL.

Front

What is the relationship between mass, volume, and density?

Back

Mass and volume are related through density; as density increases, either mass must increase or volume must decrease.
