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

Front

What is the formula for calculating density?

Back

The formula for calculating density is D = m/V, where D is density, m is mass, and V is volume.

If an object has a mass of 10 g and a volume of 2 cm³, what is its density?

Back

The density is 5 g/cm³ (D = m/V = 10 g / 2 cm³).

Front

How do you calculate mass using density and volume?

Back

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

Front

If the density of a substance is 3 g/cm³ and its volume is 4 cm³, what is its mass?

Back

The mass is 12 g (m = D × V = 3 g/cm³ × 4 cm³).

Front

What units are commonly used for density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

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

Back

Mass is directly proportional to density and volume. If density increases while volume remains constant, mass increases.

Front

If two objects have the same volume but different masses, how do their densities compare?

Back

The object with the greater mass will have a higher density, while the object with the lesser mass will have a lower density.

Front

What happens to the density of a substance if its volume increases while its mass remains constant?

Back

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

What is the density of water?

Back

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