Which is the correct definition of molarity?
Answer and explanation
Correct answer: Moles of solute per litre of solution
Molarity is defined as the number of moles of solute present per litre of solution, written as M = moles of solute/volume of solution in litres. Option B defines molality, which uses kilograms of solvent. Option C describes mass percentage, while option D describes mole fraction. Keeping the denominator clear prevents confusion among concentration units.
