Question

Formula for calculating serial dilution

Answer 1

Answer:

In serial dilutions, you multiply the dilution factors for each step. The dilution factor or the dilution is the initial volume divided by the final volume. For example, if you add a 1 mL sample to 9 mL of diluent to get 10 mL of solution, DF=ViVf = 1mL10mL=110

Answer 2

Answer:

DF = 1/20 × 1/20 × 1/20 × 1/20 = 1/160000# = 1:160 000

Best of luck
