Try this quick review. Molarity M is defined as the number of moles of solute per liter of solution. Molality m is defined as the number of moles of solute per kilogram of solvent. Although their spellings are similar, molarity and molality cannot be interchanged. Molarity is a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent. However, when the density of the solvent is significantly different than 1 or the concentration of the solution is high, these changes become much more evident. For a 1 Molar solution, 1 mol of solute is dissolved in CCl 4 until the final volume of solution is 1 L.

The primary difference between the two comes down to mass versus volume. The molality describes the moles of a solute in relation to the mass of a solvent, while the molarity is concerned with the moles of a solute in relation to the volume of a solution. Read on to learn more about molarity and molality, including their definitions, equations, and a comparison of the two terms. Molality m , or molal concentration, is the amount of a substance dissolved in a certain mass of solvent. It is defined as the moles of a solute per kilograms of a solvent.

## 8.1: Solutions and their Concentrations

The concentration of a solution is the measure of the composition of a solution. For a given solution, the amount of solute dissolved in a unit volume of solution or a unit volume of solvent is called the concentration of the solution. It can be expressed either qualitatively or quantitatively. For example, qualitatively we can say that the solution is dilute i.

Example — Calculate the molality of the solution. Calculate the molarity and molality of the solution. Calculate molality and mole fraction of sugar in the syrup.

Concentration is a very common concept used in chemistry and related fields. It is the measure of how much of a given substance there is mixed with another substance. This can apply to any sort of chemical mixture, but most frequently is used in relation to solutions, where it refers to the amount of solute dissolved in a solvent.

Solutions are homogeneous single-phase mixtures of two or more components. For convenience, we often refer to the majority component as the solvent ; minority components are solutes ; there is really no fundamental distinction between them. Solutions play a very important role in Chemistry because they allow intimate and varied encounters between molecules of different kinds, a condition that is essential for rapid chemical reactions to occur.
