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 =
