What is molarity?
Answer and explanation
Correct answer: Moles of solute in one litre of solution
Molarity is the concentration expressed as the number of moles of solute present in one litre of the final solution. Its formula is M = nsolute/Vsolution, where volume must be measured in litres. Because the denominator is solution volume, option A is correct. Option B defines molality, option C defines mole fraction, and option D is not the standard concentration definition.
