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.

Front

What is the formula to calculate Density?

Back

Density = Mass / Volume.

Front

What units are commonly used to express Density?

Back

Density is commonly expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

If an object has a mass of 50 g and a volume of 10 cm³, what is its density?

Back

Density = 50 g / 10 cm³ = 5 g/cm³.

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

Back

An object with a density less than that of water will float.

Front

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

Back

An object with a density greater than that of water will sink.

Front

What two measurements are needed to calculate Density?

Back

Mass and Volume.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

If a piece of gold has a mass of 27 g and displaces 3 mL of water, what is its density?

Back

Density = Mass / Volume = 27 g / 3 mL = 9 g/mL.
