The standard solution were prepared by transferring exactly 1.00 mL, 2.00 mL, 3.00 mL, 4.00 ml, and 5.00 ml, respectively, of stock solution to clean 100 ml vol flads, diluting to the mark with FeCl3 solution, and then filling the aoorioruatekt kabeked cuvette. Calculate the concentration of ASA

etc.

To calculate the concentration of ASA (acetylsalicylic acid), we need some additional information:

1. The concentration of the stock solution of ASA.
2. The volume of the stock solution used to prepare each standard solution.
3. The final volume of each standard solution after dilution.

Once we have this information, we can proceed with the calculations. Let's assume the concentration of the stock solution is given as C_stock (in units of concentration, e.g., mg/mL).

Here's how you can calculate the concentration of ASA:

1. Calculate the volume of ASA in each standard solution:
- For the 1.00 mL standard solution: 1.00 mL x C_stock = C1 (in units of mass, e.g., mg).
- For the 2.00 mL standard solution: 2.00 mL x C_stock = C2 (in units of mass, e.g., mg).
- For the 3.00 mL standard solution: 3.00 mL x C_stock = C3 (in units of mass, e.g., mg).
- For the 4.00 mL standard solution: 4.00 mL x C_stock = C4 (in units of mass, e.g., mg).
- For the 5.00 mL standard solution: 5.00 mL x C_stock = C5 (in units of mass, e.g., mg).

2. Calculate the final volume of each standard solution after dilution:
- The final volume of each standard solution is 100 mL.

3. Calculate the concentration of ASA in each standard solution:
- Concentration (C) = Mass (in mg) / Volume (in mL).
- For the 1.00 mL standard solution: Concentration (C1) = C1 (in mg) / 100 mL.
- For the 2.00 mL standard solution: Concentration (C2) = C2 (in mg) / 100 mL.
- For the 3.00 mL standard solution: Concentration (C3) = C3 (in mg) / 100 mL.
- For the 4.00 mL standard solution: Concentration (C4) = C4 (in mg) / 100 mL.
- For the 5.00 mL standard solution: Concentration (C5) = C5 (in mg) / 100 mL.

4. Finally, calculate the average concentration of ASA across all the standard solutions:
- Average concentration = (C1 + C2 + C3 + C4 + C5) / 5.

This will give you the concentration of ASA in the stock solution, as well as the average concentration in the standard solutions.
