Calculations in Chemistry is intended to help students overcome the challenges associated with solving the numerical problems in chemistry. Chemistry is a numerical science which cannot be fully appreciated without adequate numerical skills. In fact, the lack of problem-solving skills has been recognised as one of the major reasons for the poor performance recorded in the subject over the years. Budgetary and size constraints often translate to lack of space for solving enough sample problems in core textbooks and most problems are presented in a difficult manner that douses enthusiasm for learning. Thus, a book of this nature, containing numerous solved problems drawn from all aspects of chemistry, is necessary to complement the core texts if students are to attain the required level of mastery in the subject. Meant specifically for students studying chemistry at undergraduate and postgraduate levels, this book presents the calculations in chemistry in a simple, logical and down-to-earth manner that will impart students with the required numerical skills for excelling in chemistry. wide topical coverage clear, concise introductions that explain basic principles and theoretical basis for each type of calculation numerous representative examples practice problems and answers to test what has been explained end-of-chapter summary that gives a checklist of key terms and concepts numerous exercises, including objective questions, with answers exhaustive coverage of the mole concept use of SI units and IUPAC conventions it assumes little or no prior knowledge of chemistry and mathematics comprehensive treatment of quantitative analysis appendices that supply useful information

Calculation Methods for Industrial Hygiene Written in easy-to-understand language, students as well as practicing environmental health professionals will find that problem solving becomes a sixth sense after using Calculation Methods for Industrial Hygiene. Calculation Methods begins with a discussion of the fundamental units of mass, length, and time, and moves on to develop an understanding of the fundamental physical chemistry of gases and vapors — enabling environmental health professionals to develop new methods to solve "real world problems." Understanding of algebraic methods is the cornerstone upon which the author builds a common foundation for problem solving. After working through this book the reader will be able to:Employ dimensional analysis in solving problemsDevelop computational skills using a rigorous scientific basisIntegrate basic principles of physical chemistry with industrial hygiene, toxicology, and air pollution studiesDevelop exposure assessment dataValidate exposure assessmentsA technical and laboratory reference manual on physical chemistry and calculation techniques used in industrial hygiene and toxicology, Calculation Methods for Industrial Hygiene pays meticulous attention to the use of dimensions to solve complex problems with minimal errors. Over 180 examples and problems are completely solved and explained.

"It will be the basic aim of this book," writes Peter J. Bridge, "to impart to the reader the fundamentals of how we start with laboratory results and end up with numbers representing genetic risks." This practical guide for both clinical and research geneticists explains how to calculate an individual's genetic risk based on information available from genetic testing and from family pedigrees. Bridge begins with the general theory of estimating genetic risks, then progresses through familial and isolated cases, both simple and complex. A major strength of the book lies in the wealth of worked examples provided throughout the text. The disorders are selected to be widely applicable or adaptable as needed.New to this edition are sections on consanguinity, multipoint linkage analysis, nonparametric methods, homozygosity mapping, and physical mapping. Also new is a chapter on other DNA-based calculations, including sections on paternity, zygosity, family reconstructions, and quantification of mitochondrial mutations.From reviews of the first edition: "To use a computer package intelligently and safely, you need to have in reserve the ability to do the calculation by hand, at least approximately, so as to appreciate which factors contribute to the risk. And the current computer packages cannot cope with several factors which can crucially affect the final risk, such as germinal mosaicism or the risk of maternal cell contamination... Bridge's book is very thorough. Every combination of pedigree structure and marker data is discussed, with numerous tables showing the result of systematically varying one or more parameters." -- Journal of Medical Genetics"A useful reference book." -- American Journal of Human Genetics

A research-backed learning system for preparatory chemistry that systematically reinforces both the fundamental concepts and math skills that are prerequisites for success in general chemistry. Recent research has documented that in K–12 programs over the past decade, instruction in math computation has been de-emphasized. Calculations in Chemistry addresses these gaps in student background, applying the findings of recent scientific research on cognition, fluency in applied mathematics, and reading comprehension, to prepare students for the rigor and pace of general chemistry.

Have there been times during a chess game when you have calculated a position for half an hour, only to find out that most of what you were thinking about was of little use? If you have not, maybe the only way to improve your calculation is to upgrade your processor. But if you are human, then this book will offer you practical advice and an effective training plan to think differently and make decisions far more efficiently. In Calculation thinking methods such as Candidates, Combinations, Prophylaxis, Comparison, Elimination, Intermediate Moves, Imagination and Traps are explained to the reader, and ownership of them is offered through a carefully selected series of exercises.There is no shortcut to the grandmaster title, but there is a well-known route that many people have walked over the years. Jacob offers to guide you on part of this journey and I hope you will take him up on the offer. From the foreword by Boris Gelfand
