  • Quantitative Units of Concentration Introductory

    Rather than qualitative terms (Section 11.1 “Some Definitions”), we need quantitative ways to express the amount of solute in a solution; that is, we need specific units of concentration.In this section, we will introduce several common and useful units of concentration. Molarity (M) is defined as the number of moles of solute divided by the number of liters of solution:
