The arrangement of the given aqueous solutions of the same solute from most concentrated to least concentrated is to be stated. Concept Introduction: Solution may be defined as the mixture of a minor component which is known as solute and the major component that is known as solvent. The solute is uniformly distributed in the solvent. The solution is a liquid mixture that contains solute dissolved homogeneously in solvent. Solute is present in small amount as compared to solvent present in the solution. The molarity or concentration of the solution is defined as the total mole of the solute per unit volume of the solution. The expression for the same is, Molarity = Moles Volume L .

Concept Introduction:
Solution may be defined as the mixture of a minor component which is known as solute and the major component that is known as solvent. The solute is uniformly distributed in the solvent.
The solution is a liquid mixture that contains solute dissolved homogeneously in solvent. Solute is present in small amount as compared to solvent present in the solution.
The molarity or concentration of the solution is defined as the total mole of the solute per unit volume of the solution. The expression for the same is,
