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.

Front

What units are used to measure density?

Back

The common units for density are grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

What two measurements are needed to calculate density?

Back

Mass and Volume.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = Mass/Volume = 10g/5cm³ = 2 g/cm³.

Front

What happens to an object with a density less than 1 g/mL when placed in water?

Back

It will float.

Front

What happens to an object with a density greater than 1 g/mL when placed in water?

Back

It will sink.

Front

How do you convert density from g/cm³ to kg/m³?

Back

Multiply the density in g/cm³ by 1000.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ or 1000 kg/m³.

Front

If a rock has a mass of 30g and a volume of 10cm³, what is its density?

Back

Density = Mass/Volume = 30g/10cm³ = 3 g/cm³.

Front

What is the formula for calculating volume?

Back

Volume = Mass/Density.
