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.

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…

The Mole

One of the most important concepts to master in an introductory chemistry course is the concept of the mole, which provides chemists with a way to "count" atoms and molecules. Learn how scientists use the mole and explore the quantitative definition of this basic unit.

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.

Quantitative Reasoning in Everyday Life

Only a handful of important ideas must be mastered in order to be successful at solving chemistry problems. In this lecture, you review some basic guidelines for approaching any chemistry problem and try out your skills on a few sample problems that demonstrate how you can use everyday reasoning in…

Advanced Stoichiometry

As you move on to more advanced stoichiometry problems, you see that they can be solved using a very simple approach. You encounter three terms often applied to chemical reactions: theoretical yields, actual yields, and percent yields.

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.

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.

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.

An Introduction to Molarity

One important idea to master in any introductory chemistry course is the concept of concentration of a solution. Here, you explore this concept, the components that make up a solution, and learn about a basic unit of measurement for concentration, molarity.

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…

Solubility Equilibriaâ€”Common Ion Effect

Your study of solubility equilibria continues with some advanced practice problems. Here, you encounter the last major type of equilibrium problem. To solve these problems, you revisit Le Chatelier's Principle and learn about some of the pitfalls to avoid when dealing with these kinds of equilibrium systems.
