Molar Analytical Concentration

  The molar analytical concentration, or for the sake of brevity, just analytical concentration, of a solution gives the total number of moles of a solute in 1 liter of the solution (or the total number of millimoles in 1 mL). In other words, the molar analytical concentration specifies a recipe by which the solution can be prepared regardless of what might happen to the solute during the solution process. Note that in Example below, the molar concentration that we calculated is also the molar analytical concentration c C₂H₅OH = 0.0143 M because the solute ethanol molecules are intact following the solution process.

  In another example, a sulfuric acid solution that has an analytical concentration of c H₂SO₄ = 1.0 M can be prepared by dissolving 1.0 mole, or 98 g, of H₂SO₄ in water and diluting the acid to exactly 1.0 L. As we shall see, there are important differences between the ethanol and sulfuric acid examples.
