Mass, Volume, and Density

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams (g) or kilograms (kg).

Front

What is volume?

Back

Volume is the amount of space that an object or substance occupies, usually measured in liters (L) or milliliters (mL).

Front

What is density?

Back

Density is the mass of an object divided by its volume, often 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 formula for the volume of a rectangular box?

Back

Volume = Length × Width × Height.

Front

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

Back

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

Front

What unit is commonly used to measure volume in liquids?

Back

Milliliters (mL) or liters (L).

Front

What is the relationship between mass and density?

Back

For a given volume, as mass increases, density increases; for a given mass, as volume increases, density decreases.

Front

If two objects have the same volume but different masses, which one has a higher density?

Back

The object with the greater mass has a higher density.

Front

What is the volume of a liquid in a graduated cylinder if it reads 30 mL?

Back

The volume of the liquid is 30 mL.
