Which statement correctly uses molarity?
Answer and explanation
Correct answer: Moles of solute in 1 litre of solution
Molarity is the amount of solute in moles per litre of the final solution: M = n(solute)/V(solution in L). Therefore option A states the correct definition. The volume belongs to the whole solution, not merely the solvent. Option B is not molarity and does not correctly define molality either, while C concerns an observable property and D is not a standard concentration measure. Thus only A is scientifically valid.
