If two solutions have the same volume, which has the lower concentration?
Answer and explanation
Correct answer: The one with fewer moles of solute
For a fixed volume, molarity is proportional to the moles of solute: M = n/V. Therefore, among equal-volume solutions, the one containing fewer moles of solute has the lower concentration. A dilute solution need not contain absolutely zero solute, and mass alone cannot be compared without knowing the substance’s molar mass.
