3rd Edition
Chemical Calculations Mathematics for Chemistry, Third Edition
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.
Features
◾ 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.

Biography
Paul Yates has a BSc in Chemical Physics, a PhD in Chemistry and an MA in Learning and Teaching in Higher Education. After several years lecturing in physical chemistry at Keele University he moved into educational development. He was subsequently able to combine this experience in the post of Discipline Lead for the Physical Sciences at the Higher Education Academy.
He has a long standing interest in the development of mathematical skills and is the author of two textbooks on mathematics for chemists. Since returning to the university sector at Newman University he has developed an interest in the way in which data and metrics is used by various stakeholders including student supporters.
He received a Keele University Excellence in Teaching Award, is a Fellow of the Royal Society of Chemistry, a Senior Fellow of the Staff and Educational Development Association, and a Principal Fellow of the Higher Education Academy.
