Chemical Calculations by Yates, Paul C.;

Rövid leírás:

Many undergraduate students enter into chemistry courses, often possessing low levels of experience with the mathematical concepts necessary for carrying out applied calculations in chemistry. This third Edition provides a unified, student-friendly guide of mathematical concepts and techniques structured in the context of familiar chemical topics.

Hosszú leírás:

Uniquely organized by chemical rather than mathematical topics, this book relates each mathematical technique to the chemical concepts where it applies. The new edition features additional, revised, and updated material in every chapter and maintains the clarity of the previous edition with the appropriate organization of topics and improved cross-referencing where mathematical techniques occur more than once. The text contains additional worked examples and end-of-chapter exercises with detailed solutions?giving students the opportunity to apply previously introduced techniques to chemically related problems. It is an ideal course companion for chemistry courses throughout the length of a degree.

? This book covers the difficult area of mathematics in an easy-to-read format for students

and professionals in chemistry and related subjects.

? Structured according to chemical rather than mathematical topics.

? Each topic has at least 12 end of chapter applied chemistry problems to provide practice

in applying the techniques to real chemistry.

? Indexing of material by both chemical and mathematical topics.

? Extends its utility as a concise and practical reference for professionals in a wide array of

scientific disciplines involving chemistry.
