12. Matching: A serial dilution series is made where each tube is diluted 1:4. Tube 1 contains 1 mL of undiluted sample, which is added to diluent in tube 2 and

so on. If the original concentration was 6142 mg/dL, what is the concentration in each tube? Match the correct concentration to each tube. Tube 1 = Tube 2 = Tube 3 = Tube 4 = Tube 5=
