Understand that molarity is defined as the number of moles of solute dissolved in one liter of solution.
Recall the formula for molarity: \(M = \frac{\text{moles of solute}}{\text{liters of solution}}\).
Identify the units involved: moles (mol) for the amount of substance and liters (L) for the volume of solution.
Recognize that molarity is expressed as moles per liter, which corresponds to the unit \(\text{mol/L}\).
Compare the given options and confirm that \(\text{mol/L}\) correctly represents molarity, while the others represent different concentration units or are incorrect.
