Three different solutions were prepared in the laboratory. One was prepared by dissolving 82 g of KCI in enough water to make 300 milliliters of solution. Another was prepared by diluting 150mL of 8.0 molar of KCI to 500 mL. The third solution was prepared by aliquoting 5 mL each from the first two solutions and diluting it to 50mL. If 25 mL aliquot from the first solution, 20 ml aliquot from the second solution and 30 mL aliquot from the third solution were mixed. What is the concentration of the final solution?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
