Why must the tablet and the pure ASA be diluted twice?

The tablet and pure acetylsalicylic acid (ASA) must be diluted twice to ensure accurate concentration and effective solubility for testing or administration. The first dilution allows for a manageable concentration that can be easily measured, while the second dilution helps achieve the final desired concentration for optimal results. This stepwise dilution process minimizes the risk of errors and enhances the reliability of the experimental or clinical outcome.
