Every result a laboratory produces rests on a solution that somebody prepared correctly, and every solution rests on a calculation.

Basics of Chemical Calculations is a bench-side handbook for chemistry students and new laboratory analysts who know the theory but freeze in front of a bottle of 35% hydrochloric acid. It was written by an analytical chemist who spent his first years at the bench teaching colleagues how to turn "prepare 250 ml of 0.1 N" into a number on the balance.

More than 100 numericals are solved step by step in one simple layout: what is given, the formula, the substitution, the answer, and what to do at the bench. All the working formulas are collected in a summary arranged by task.

Covers: the atom, molecular weight and the mole; equivalent weight; units, significant figures and specific gravity; molarity, normality, molality and mole fraction; ppm, ppb and ppt; % w/w, % w/v and % v/v; molarity of commercial acids and bases; dilution; stoichiometry, limiting reagent, yield and hydrates; titration, standardisation, factor and back titration; pH, buffers and the pH meter.

Includes quick-reference tables of commercial reagent strengths and atomic masses, practice problems after every chapter with an answer key, and a complete formula summary.

For B.Sc. and M.Sc. chemistry students, pharmacy and biotechnology students, QC and QA analysts, and anyone preparing solutions in a laboratory.
