DILUTIONS AND STANDARDS

1/4 x 2/4 x 2/4 x 2/4 x 2/4 x 2/4 x 2/4 x 2/4 = 1/512 . Both example 1 and example 2 illustrate how the same serial dilution problem may be expressed in two different ways. In the first example a step-by-step procedural outline is provided. Go back and look at example 1. In the first tube 1 mL of serum was added to 3 mL of saline. ................
