Chemistry - the Complete Course Series, teaches students quantitative reasoning to solve chemistry problems. The 30 volume series covers all aspects of Chemistry from density to the mole, to molarity, stoichiometry and equilibrium. It demonstrates how to ask meaningful questions and conduct careful investigations to build knowledge of chemical and physical concepts and develop the skills to solve mathematical and scientific problems. Stoichiometry is the study of the quantitative relationships that exist between substances involved in a chemical reaction. The key to solving all stoichiometry problems is the balanced chemical equation for the reaction. There are several "different" types of stoichiometry problems that you need to be able to solve. This volume teaches all stoichiometry problems are really very similar and the same general approach can be used to solve any of them. There are four "basic" types of stoichiometry problems. Students must understand what is represented by the coefficients in the balanced chemical equation.
