This chapter describes the factors that determine the solubility of a solute and the rate at which a solute dissolves. You will learn the five methods commonly used to express the concentrations of solutions. You will also learn how the properties of a solution change when the number of particles dissolved in it is changed. Finally, you will learn how to use changes in boiling and freezing points to determine the molar mass of a substance.

In this chapter, you will learn: to identify the factors that determine the rate at which a solute dissolves to calculate the solubility of a gas in a liquid to solve problems involving the molarity of a solution to explain percent by volume and percent by mass solutions to explain why a solution has a lower vapor pressure than a pure solvent to calculate the molality and the mole fraction of a solution
