검증된 단계별 안내1
Understand that molarity is defined as the number of moles of solute dissolved per liter of solution.
Recall the formula for molarity: \(M = \frac{\text{moles of solute}}{\text{liters of solution}}\).
Recognize that the unit for molarity is therefore moles per liter, often written as mol/L.
Compare the given options: mol/L, g/L, ppm, and mol/kg, and identify which matches the molarity definition.
Conclude that mol/L is the most common and correct unit for expressing molarity.
