The solution that has the highest molarity is to be determined. Concept introduction: Molarity ( M ) is one of the concentration terms that determine the number of moles of solute present in per litre of solution. Unit of molarity is mol / L . The expression to calculate the molarity of solution when moles of solute and volume of solution are given is as follows: Molarity of solution ( M ) = moles of solute ( mol ) volume of solution ( L )
