Verified step by step guidance1
Understand that molarity is a measure of concentration defined as the number of moles of solute dissolved in one liter of solution.
Recall the formula for molarity: \(\text{Molarity} = \frac{\text{moles of solute}}{\text{liters of solution}}\).
Analyze each unit option: \(\text{g/L}\) represents grams per liter, which is mass concentration, not molarity.
The unit \(\text{L/mol}\) is the inverse of molarity and does not represent concentration.
The unit \(\text{mol/kg}\) corresponds to molality, which is moles of solute per kilogram of solvent, not molarity.
