Ans. To prepare a dilute solution from a concentrated solution, you can use the following formula:C1V1 = C2V2Where:C1 = Concentration of the concentrated solutionV1 = Volume of the concentrated solutionC2 = Desired concentration of the dilute solutionV2 = Volume of the dilute solutionBy rearranging the formula, you can calculate the volume of the concentrated solution needed to prepare the desired dilute solution.
