Density Calculations

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

Front

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass (g) / Volume (cm³).

Front

What are the units of density?

Back

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

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What happens to an object with a density less than water?

Back

An object with a density less than water (1 g/cm³) will float.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water (1 g/cm³) will sink.

Front

What two measurements are needed to calculate density?

Back

Mass and Volume.

Front

What is the density of a solid ball with a mass of 50 grams and a volume of 20 cm³?

Back

Density = 50g / 20cm³ = 2.5 g/cm³.

Front

What is the mass of an object if its density is 3 g/cm³ and its volume is 4 cm³?

Back

Mass = Density x Volume = 3 g/cm³ x 4 cm³ = 12g.

Front

What is the volume of an object if its mass is 30g and its density is 6 g/cm³?

Back

Volume = Mass / Density = 30g / 6 g/cm³ = 5 cm³.
