Calculating Density Practice

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is 1 g/cm³.

Front

Which substances float in water?

Back

Substances with a density less than 1 g/cm³ float in water.

Front

If an object has a mass of 50 grams and a volume of 25 cm³, what is its density?

Back

Density = 50 g / 25 cm³ = 2 g/cm³.

Front

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

Back

It sinks.

Front

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

Back

It floats.

Front

If a solid object has a mass of 100 grams and a volume of 50 cm³, what is its density?

Back

Density = 100 g / 50 cm³ = 2 g/cm³.

Front

What is the formula for calculating the volume of an irregular object using water displacement?

Back

Volume = Final water level - Initial water level.

Front

If an object displaces 25 mL of water, what is its volume?

Back

The volume of the object is 25 mL.
