21. Practice: You perform a serial dilution, using a known concentration of 100 mg/mL in the first tube. Each tube contains 100 µL of diluent.
You withdraw 50 µL from tube 1 and add it to tube 2, and continue with the same dilution protocol for the subsequent tubes. When you reach
tube 11, you discard the 50 µL, leaving 100 µL of diluent in tube 12. List the values of the standard curve found in each well:
