During the preparation of a solution, a solute is dissolved in a volume of solvent smaller than the desired volume of solution. Subsequently, solvent is added until the final volume of solution is reached. Discuss the importance of dissolving the solute in a volume of solvent inferior to the total volume of solution desired.
