Calculating Density Practice

Front

What is Density?

Back

Density is the mass of an object divided by its volume. It is usually expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

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

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

Back

Density = 10g / 5cm³ = 2g/cm³.

Front

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

Back

The density increases.

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

Back

The density decreases.

Which of the following substances would float in water? (Hint: water has a density of 1g/cm³) - gold, rubber, water, cork

Back

Cork would float in water.

What is the density of a plastic ball that has a volume of 6cm³ and a mass of 12g?

Back

Density = 12g / 6cm³ = 2g/cm³.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.

How much water has been displaced if a solid object is submerged and the water level rises from 40 mL to 65 mL?

Back

The water displaced is 25 mL.
