About This Chapter
CEOE Physical Science: The Mole Concept - Chapter Summary
Depending on how much you remember about the mole concept from your prior studies, you might go through the chapter's text and video lessons once or multiple times in preparation for the CEOE Physical Science examination. Revisit the methods by which atoms are measured, re-discover strategies for calculating molar mass and measuring molecules, and find out more about how to illustrate the Avogadro's law equation. Your review of this chapter could result in your ability to:
- Use Avogadro's number when counting
- Calculate gas and molar volume with Avogadro's law
- Define and apply the molar mass formula
Fun and animated, the video lessons can be viewed online with just a Web-connected mobile device. Text lessons consist of written material on the mole concept along with multiple-choice quizzes and a 'course' tab. The self-assessment quizzes are short and simple. Click an answer to indicate your choice, then choose 'next.' Your results will be automatically tallied. If you missed a question, you can take the test again or locate the correct answer within the video or lesson transcript.
CEOE Physical Science: The Mole Concept Chapter Objectives
You'll need a score of 240 to pass the computer-administered CEOE Physical Science examination, which has three subareas and one constructed-response section. Subarea III, Structure of Matter and Changes in Matter, is where you'll express your clear comprehension of Avogadro's number, the mole concept and related formulas and equations. The subarea is worth 29% of the assessment. With regards to the overall examination, you should be prepared to answer 80 selected-response questions and to complete one constructed-response assignment on your way to earning a teaching license. You must observe a four-hour testing time limit.
1. Avogadro's Number: Using the Mole to Count Atoms
How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.
2. Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas
Have you ever wondered why a balloon expands when you blow it up? How something as light as air is able to exert a force large enough to inflate a balloon? In this lesson, you will learn about the relationship between the volume of a container filled with a gas and the number of gas particles that container holds. This relationship is known as Avogadro's Law.
3. What is Molar Mass? - Definition, Formula & Examples
Compounds have mass, and this is what we call the molar mass. In this lesson, we will discuss the molar mass and go over examples on how to calculate it.
