Calculating Density

Front

What is density?

Back

Density is a measure of mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass / Volume.

Front

What are the units of density?

Back

The common units for density are grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

If an object has a mass of 50g and a volume of 10cm³, what is its density?

Back

Density = 50g / 10cm³ = 5 g/cm³.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

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

Back

If the mass increases and the volume remains constant, the density of the object increases.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.

Front

How do you find the volume of an irregularly shaped object using water displacement?

Back

To find the volume, submerge the object in water and measure the change in water level; the volume is equal to the increase in water level.

What is the density of a substance with a mass of 300g and a volume of 50cm³?

Back

Density = 300g / 50cm³ = 6 g/cm³.

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = Length × Width × Height.
