Chemistry, 2nd Edition

In this first episode, Professor Cardulla explains how any student can find success in chemistry by cultivating a meaningful understanding of the concepts and quantitative thinking operations that underlie this often challenging area of study. #Science & Mathematics

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.

Only a handful of important ideas must be mastered in order to be successful at solving chemistry problems. In this episode, 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 your chemistry class.

Building on the ideas explored in the first three episodes, 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.

Continue to lay a strong foundation for your understanding of chemistry by learning about one of the key tools you'll be using: the International System of Units (SI), or the metric system. This episode explains why this system is so useful to scientists and lays out the prefixes and units of measurement that make up the metric system.

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.
