A relevant, problem-solving approach to chemistry

The Third Edition of Principles of Chemistry: A Molecular Approach presents core concepts without sacrificing rigor, enabling students to make connections between chemistry and their lives or intended careers. Drawing upon his classroom experience as an award-winning educator, Professor Tro extends chemistry to the student’s world by capturing student attention with examples of everyday processes and a captivating writing style. Throughout this student-friendly text, chemistry is presented visually through multi-level images that help students see the connections between the world around them (macroscopic), the atoms and molecules that compose the world (molecular), and the formulas they write down on paper (symbolic).

The Third Edition improves upon the hallmark features of the text and adds new assets–Self Assessment Quizzes, Interactive Worked Examples, and Key Concept Videos–creating the best learning resource available for general chemistry students.
