Document Summary

Frequently, scientists work with solutions rather than solids. You will encounter problems and situations in this course, other courses, and many jobs, where you need to know the concentration of a solution. Molarity is a very important concept and is used in a wide variety of calculations, from simple solution preparation, to dilution of solutions, to stoichiometry of reactions in solution and quantitative analysis of unknown solutions. It is possible to determine the number of moles of a substance present in a solution mixture, from the volume and concentration of the solution used. To become familiar with molarity as a concentration unit. To learn how to prepare solutions with a specified molarity. To be able use molarity and volume to solve stoichiometric problems. Solubility, net ionic equations and molarity (through model 5a) Molarity is the link between moles of solute and volumes of solution.
