Understand that concentration in chemistry typically refers to the amount of solute present in a given volume of solution.
Recognize that common units for concentration include mass per volume (like g/L) and amount of substance per volume (like mol/L).
Recall that mol/L (moles per liter) is the standard unit for molarity, which expresses concentration as the number of moles of solute dissolved in one liter of solution.
Note that kg/mol is a unit of molar mass, not concentration, and atm is a unit of pressure, not concentration.
Conclude that mol/L is the most appropriate and commonly used unit to express the concentration of a solution in chemistry.
