Solving Molarity Problems

Extend your understanding of molarity by solving some typical problems encountered in the high school chemistry classroom. To foster your understanding of these problems, you are asked to draw upon the quantitative reasoning skills you previously used.

Solving Mole Problems

By solving problems involving moles, you refine the quantitative techniques introduced in earlier lectures while increasing your familiarity with this important chemical value.

Basic Concepts of Quantitative Reasoning

Introductory chemistry is not mysterious: It requires simple quantitative reasoning that comes naturally to most students. You learn about the types of numbers involved in chemistry and how to solve problems commonly encountered in high school chemistry.

An Introduction to Stoichiometry

What are the quantitative relationships between the substances in a chemical reaction? The study of stoichiometry shows you how to apply your ability to balance equations to solve problems involving chemical reactions.

Chemistry, 2nd Edition Course

Many students struggle in high school chemistry. Even if they succeed in earning a good grade, they often still feel confused and unconfident. Why is this? And what can be done to help every student succeed in this vitally important course? Success in chemistry, according to veteran science teacher Professor…

Quantitative Reasoning in Chemistryâ€”Density

Building on the ideas explored in the first three lectures, you examine a fundamental quantitative measurement in chemistry, density, and explore the real-world meaning of this measurement. You then solidify your understanding of this concept by working some basic density problems.

Percent Composition and Empirical Formulas

In this lecture, you encounter two "classic" types of chemistry problems and learn the basic characteristics of each. The lecture concludes with several practice problems to help you master the skill of solving percent composition problems.

Putting It All Together

In this final lecture, you tackle problems that require you to pull together all the knowledge you've acquired. Through these challenging problems, you build confidence in your ability to unravel new problems and pursue more advanced levels of chemistry.

Converting between Systems of Measurement

Now that you have established an understanding of the SI system, put your knowledge to work as you practice converting units from one system of measurement to another. You hone your conversion skills by working several sample problems.

Advanced Molarity Problems

You are asked to take the concepts you learned about molarity in the last two lectures and apply them to a number of unfamiliar problems. These problems offer an opportunity to test your comprehension of the concepts you've been exploring.

An Introduction to Equilibrium Problems

You use your basic understanding of equilibrium systems to try to solve some problems. You tackle two kinds of equilibrium problems: ones in which you are asked to calculate the equilibrium constant for an equation, and ones in which you are asked to find the equilibrium concentration of a reactant…

Weak Acids and Bases

Look at weak acids and bases, compounds that are only slightly ionized in water-based solutions. You learn how to solve the "classic" weak acid problem and apply the same approach to weak base problems.
