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. In this program we will apply what we learned about molarity and apply this knowledge to a few additional types of problems. Solving any of these problems correctly can be an indication of mastery of both the specific concepts previously covered as well as the general approach to thinking about problems. In this volume special "formulas" are presented for solving the specific problems. Some of the problems solved are given specific names, such as "dilution" problems.
