Key Concepts

Dilution Principle

The dilution principle involves mixing a known quantity of a substance with a solvent to decrease its concentration. In this context, it requires understanding that the total amount of solute remains unchanged while the volume increases, resulting in a lower concentration of the substance per unit volume.

Total Quantity Calculation

Total quantity calculation is the process of determining the overall amount of a substance present in a solution by multiplying the concentration of the substance by the volume of the solution from which it came. This calculation is crucial before the dilution step to ensure that the original amount is preserved during the mixing process.

Final Concentration Determination

Final concentration determination involves dividing the total amount of the substance by the total volume of the diluted solution. This key concept applies the principle of conservation of mass to find the new concentration after mixing solutions of different volumes.

Calculate the number of units per milliliter if a $6 \mathrm{~mL}$ vial of heparin containing 100,000 units $/ \mathrm{mL}$ is injected into $500 \mathrm{~mL}$ of normal saline solution.
