Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

How do you calculate the density of an object?

Back

To calculate density, divide the mass of the object by its volume. The formula is: Density = Mass (g) / Volume (mL or cm³).

Front

What is the unit of density in the metric system?

Back

The unit of density in the metric system is grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³).

If an object has a mass of 100 g and occupies a volume of 20 mL, what is its density?

Back

Density = Mass/Volume = 100 g / 20 mL = 5 g/mL.

Front

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

Back

If the mass increases while the volume remains constant, the density of the object increases.

Front

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

Back

If the volume increases while the mass remains constant, the density of the object decreases.

Front

How can you determine the density of an irregularly shaped object?

Back

To determine the density of an irregularly shaped object, measure its mass and then use water displacement to find its volume. Density = Mass/Volume.

Front

What is the principle of water displacement?

Back

The principle of water displacement states that the volume of water displaced by an object submerged in water is equal to the volume of the object.

If a liquid has a density of 1.5 g/mL, will it float or sink in water?

Back

If a liquid has a density of 1.5 g/mL, it will sink in water because it is denser than water (1 g/mL).

Front

What is the density of pure water?

Back

The density of pure water is approximately 1 g/mL at 4°C.
