Final answer:
The question concerns the mixing of two saline solutions to create a 3% hypertonic saline solution for use as an inhalator. The dilution equation C1V1 = C2V2 is used to determine how to prepare the solution, but exact proportions cannot be determined without additional information on desired total volume.
Step-by-step explanation:
The question involves the preparation of a hypertonic saline solution at 3% concentration using two available saline solutions of different concentrations (0.45% and 20%). This is a common scenario in medical and pharmaceutical settings, often related to the preparation of solutions for use as an inhalator to deliver medications via inhalation. The process requires calculations to determine the correct proportions of the starting solutions to mix in order to achieve the desired final concentration. In general, to prepare a new solution from stock solutions of different concentrations, you would use the dilution equation:
C1V1 = C2V2
Where C1 and C2 are the concentrations of the original solutions and the desired final concentration, respectively, and V1 and V2 are the volumes of the original solutions and the final solution, respectively. However, since you have not provided information on the total volume to be achieved or the constraints for the volume of each stock solution used, the exact proportions and method to obtain the 2ml of 3% saline cannot be given.
