Density Semester Exam Review Fall 2024

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 formula to find mass if density and volume are known?

Back

Mass = Density × Volume.

Front

What is the formula to find volume if density and mass are known?

Back

Volume = Mass / Density.

Front

If an object has a mass of 48 grams and a volume of 24 cm³, what is its density?

Back

Density = 48 g / 24 cm³ = 2 g/cm³.

Front

What does it mean if an object is denser than water?

Back

It means the object will sink in water, as its density is greater than 1 g/cm³.

Front

What does it mean if an object is less dense than water?

Back

It means the object will float in water, as its density is less than 1 g/cm³.

Front

If a paper clip has a mass of 9g and a volume of 3cm³, what is its density?

Back

Density = 9 g / 3 cm³ = 3 g/cm³.

Front

What is the density of a rock with a mass of 14g and a volume of 2cm³?

Back

Density = 14 g / 2 cm³ = 7 g/cm³.

Front

If an eraser has a mass of 4g and a volume of 2cm³, what is its density?

Back

Density = 4 g / 2 cm³ = 2 g/cm³.
