Students apply the Ideal Gas Law to determine the molar mass of an unknown gas found in a common household product.
This printable education experiment contains a detailed teachers' guide, 2-page student information sheet, and single-page student question worksheet for printing and distributing in the classroom.
Age Level
This experiment is designed for ages 14-18. It can be adapted for ages 11-13.
Subject
Gases and the Kinetic-Molecular Theory, science as inquiry and data analysis.
Purpose(s)
- 1. To demonstrate the use of the Ideal Gas Law, Daltons’ Law of Partial Pressures, and the Kinetic Theory of Gases.
- 2. To determine the molar mass and formula of a gas from the measured properties of gases.
- 3. To have students analyze data that has been collected using laboratory equipment (balances).
