Calculating Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula to find the volume of an irregular object using water displacement?

Back

Volume of the object = Final water level - Initial water level.

Front

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

Back

Density = 50 g / 10 mL = 5 g/mL.

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.

Front

If a stone displaces 30 mL of water, what is its volume?

Back

The volume of the stone is 30 mL.

Front

What is the density of an object that has a mass of 100 g and displaces 25 mL of water?

Back

Density = 100 g / 25 mL = 4 g/mL.

Front

What is the significance of density in identifying materials?

Back

Different materials have unique densities, which can help identify them based on their mass and volume.

Front

If an object is less dense than water, what will happen when it is placed in water?

Back

It will float.

Front

If an object is more dense than water, what will happen when it is placed in water?

Back

It will sink.
