Solving Density Problems (Math Review)

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 (D) = Mass (M) / Volume (V).

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 12g and a volume of 6mL, what is its density?

Back

The density is 2 g/mL.

Front

How do you find the density of an object?

Back

To find the density of an object, divide its mass by its volume: Density = Mass / Volume.

Front

What is the density of a paperclip with a mass of 9g and a volume of 3 cm³?

Back

The density is 3 g/cm³.

Front

If an object has a mass of 500g and a volume of 25mL, what is its density?

Back

The density is 20 g/mL.

Front

What is the density of an eraser with a mass of 4g and a volume of 2cm³?

Back

The density is 2 g/cm³.

Front

What units are used to measure density?

Back

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

Front

If an object has a density of 1 g/cm³, what does that imply about its buoyancy in water?

Back

An object with a density of 1 g/cm³ will float in water, as it is less dense than water.

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 will increase.
