The materials listed in the table below are called elements. They are substances found in nature. Some are metals, like aluminum, copper, iron, lead, silver, tin, and nickel. Some are gases, such as hydrogen and oxygen.

We use all of these elements in everyday life. Pennies were originally made of copper, quarters were silver, and nickels were made of nickel. Most soda cans are aluminum. Water is made of hydrogen and oxygen, and we breathe oxygen. Salt is mostly made of sodium.

Think about these materials and how heavy they would feel if you had a cubic centimeter of each one.

For each material listed in the table, find the mass for 1,000 cm³ in grams and kilograms. Then find the weight in pounds. Which material is the densest and which is the least dense? Why do you think this is true?

| Material | Density (g/cm³) | Mass in g for 1,000 cm³ | Mass in kg for 1,000 cm³ | Weight in Pounds |
|----------|-----------------|-------------------------|--------------------------|------------------|
| Aluminum | 2.70 | | | |
| Copper | 8.96 | | | |
| Hydrogen | 0.00009 | | | |
| Iron | 7.87 | | | |
| Lead | 11.34 | | | |
| Nickel | 8.91 | | | |
| Oxygen | 0.0013 | | | |
| Silver | 10.50 | | | |
| Sodium | 0.97 | | | |
| Tin | 7.29 | | | |

To find the mass for cm3 in grams and kilograms, and the weight in pounds, you can use the following steps:

Find the density of the material: The density of each material is listed in the first column of the table, in g/cm³.

Multiply the density by 1,000 to find the mass in grams for 1,000 cm³: For example, the density of aluminum is 2.7 g/cm³. To find the mass of 1,000 cm³ of aluminum, multiply 2.7 by 1,000: 2.7 g/cm³ * 1,000 cm³ = 2,700 g.

Divide the mass in grams by 1,000 to find the mass in kilograms: For example, the mass of 1,000 cm³ of aluminum is 2,700 g. To find the mass in kilograms, divide 2,700 by 1,000: 2,700 g / 1,000 g/kg = 2.7 kg.

Multiply the mass in kilograms by 2.20462 to find the weight in pounds: For example, the mass of 1,000 cm³ of aluminum is 2.7 kg. To find the weight in pounds, multiply 2.7 by 2.20462: 2.7 kg * 2.20462 lb/kg = 5.95 lb.
