Calculating Density Practice Problems

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 D = m/v, where D is density, m is mass, and v is volume.

Front

How do you calculate density?

Back

Density is calculated using the formula D = m/v, where D is density, m is mass (in grams), and v is volume (in cubic centimeters or milliliters).

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

If an object has a mass of 100g and a volume of 50cm³, what is its density?

Back

Density = mass/volume = 100g/50cm³ = 2g/cm³.

Front

What is the relationship between mass, volume, and density?

Back

Mass, volume, and density are related by the formula D = m/v. If you know any two of these values, you can calculate the third.

Front

How does temperature affect density?

Back

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

Front

What is the density of water?

Back

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

Front

If an object floats in water, what can you infer about its density?

Back

If an object floats in water, its density is less than that of water (1 g/cm³).

Front

What is the formula to find mass if density and volume are known?

Back

Mass can be calculated using the formula m = D × v, where D is density and v is volume.

Front

Calculate the density of a cube with a mass of 50g and a volume of 100cm³.

Back

Density = mass/volume = 50g/100cm³ = 0.5g/cm³.
