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. The Factor-Label approach to solving problems is one of the most powerful methods ever designed to obtain the answer to a simple problem. It's power lies in the fact that it is possible to obtain the correct answer without having to understand anything about the quantities involved in the problem other than their units. This volume teaches not to ignore the necessity to develop the important conceptual understandings required to do well in chemistry. It is an excellent method to convert one unit of measurement to another. To do "classic" types of unit conversions as well as work conversions that involve raising units to some power.
