Document Summary
The concentration of a solute is the amount of solute dissolved in a given quantity of. The quantity of solvent or solution can be expressed in terms of volume or in terms of mass or molar amount. Thus, there are several ways of expressing the concentration of a solution. the molarity of a solution is the moles of solute in a liter of solution. This unit is especially useful when you wish to dispense a given amount of solute, because the unit directly relates the amount of solute to the volume of solution. Some other concentration units are defined in terms of the mass or molar amount of solvent or solution. The most important of these are mass percentage of solute, molality, and mole fraction. Solution concentration is sometimes expressed in terms of the mass percentage of solute that is, the percentage by mass of solute contained in a solution.
