## Density Calculation Worksheet

When it comes to understanding the concept of density, many students struggle with the calculations involved. Density is defined as the mass of an object per unit volume, and it is a crucial concept in science and engineering. In this worksheet, we will go through some examples of how to calculate density and provide practice problems for you to work on. By the end of this worksheet, you will have a solid understanding of how to calculate density and be able to apply this knowledge to real-world situations.

## Understanding Density

Density is a fundamental property of matter that describes how much mass is contained within a given volume. The formula for calculating density is:

Density = Mass / Volume

Where:

- Density is the mass of an object per unit volume
- Mass is the amount of matter in an object
- Volume is the amount of space that an object occupies

Typically, the unit of mass is grams (g) or kilograms (kg), and the unit of volume is cubic centimeters (cm³) or cubic meters (m³). The unit of density is often expressed as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

## Example Calculations

Let’s walk through a couple of examples to illustrate how to calculate density:

### Example 1:

You have a block of wood that has a mass of 100 grams and a volume of 50 cm³. What is the density of the block?

Using the formula Density = Mass / Volume:

Density = 100 g / 50 cm³ = 2 g/cm³

Therefore, the density of the block of wood is 2 grams per cubic centimeter.

### Example 2:

You have a metal sphere with a mass of 500 grams and a volume of 100 cm³. What is the density of the metal?

Using the formula Density = Mass / Volume:

Density = 500 g / 100 cm³ = 5 g/cm³

Therefore, the density of the metal sphere is 5 grams per cubic centimeter.

## Practice Problems

Now it’s time for you to practice calculating density on your own. Below are some practice problems for you to work through:

### Problem 1:

You have a container filled with water that has a mass of 500 grams and a volume of 1000 cm³. What is the density of the water?

### Problem 2:

You have a block of iron with a mass of 1000 grams and a volume of 250 cm³. What is the density of the iron block?

### Problem 3:

You have a cube made of plastic with a mass of 300 grams and a volume of 150 cm³. What is the density of the plastic cube?

## Answers

### Problem 1:

Using the formula Density = Mass / Volume:

Density = 500 g / 1000 cm³ = 0.5 g/cm³

Therefore, the density of the water in the container is 0.5 grams per cubic centimeter.

### Problem 2:

Using the formula Density = Mass / Volume:

Density = 1000 g / 250 cm³ = 4 g/cm³

Therefore, the density of the iron block is 4 grams per cubic centimeter.

### Problem 3:

Using the formula Density = Mass / Volume:

Density = 300 g / 150 cm³ = 2 g/cm³

Therefore, the density of the plastic cube is 2 grams per cubic centimeter.

## Conclusion
