Which option gives the correct definition of molarity?
Answer and explanation
Correct answer: Moles of solute per litre of solution
Molarity, represented by M, is defined as the number of moles of solute present in one litre of solution: M = nsolute/Vsolution in litres. The denominator refers to the final volume of the complete solution, not the volume of solvent alone. Option B describes molality, which uses kilograms of solvent. The other two expressions do not represent a standard concentration definition.
