SUMMARY
The discussion clarifies the distinction between molarity and concentration. Concentration is a broad term that quantifies the amount of solute in a solution, which can be expressed in various ways, including molarity, molality, mass/volume fraction, and molar fraction. Molarity, denoted as M, specifically measures the number of moles of solute per liter of solution and is temperature-dependent, while molality, denoted as m, measures moles of solute per kilogram of solvent and is temperature-independent. Thus, molarity and molality are not merely special cases of concentration; they are specific measures within the broader concept of concentration.
