If $100 \mathrm{~mL}$ of a Choledyl ${ }^D$ elixir containing $10 \mathrm{mg} / 5 \mathrm{~mL}$ active ingredient (oxtriphylline) is diluted to $500 \mathrm{~mL}$, what will be the final strength of oxtriphylline?

Key Concepts

Concentration of Solutions

This concept involves understanding that the concentration of a solution is the amount of solute (active ingredient) per unit volume of the solution. It is typically expressed in units such as mg/mL. Knowing the original concentration allows professionals to determine how much active ingredient is present in any given volume of the solution.

Dilution Principle

The dilution principle states that when a solution is diluted, the total amount of the active ingredient remains constant while the volume increases. This decrease in concentration is directly proportional to the increase in volume, which requires adjusting the concentration accordingly.

Proportional Reasoning in Dilutions

Proportional reasoning is used to calculate the final concentration after dilution. It involves setting up a ratio between the amount of active ingredient and the volume of the solution before and after dilution, ensuring that the product of the concentration and volume (the total amount of the active ingredient) remains constant.
