Mass, Volume and Density

Front

What is the definition of density?

Back

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

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

If an object has a density less than 1 g/mL, what will happen when it is placed in water?

Back

It will float.

Front

What is the relationship between mass and volume in determining density?

Back

Density is directly proportional to mass and inversely proportional to volume.

Front

What unit is commonly used to measure mass?

Back

Grams (g).

Front

What unit is commonly used to measure volume?

Back

Milliliters (mL) or cubic centimeters (cm³).

Front

If an object has a density of 2.5 g/cm³, will it sink or float in water?

Back

It will sink, as its density is greater than that of water (1 g/cm³).

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

Front

What is the mass of 100 mL of water, given that the density of water is 1 g/mL?

Back

100 grams.
