You conduct the following serial dilution: Step 1: You’ve diluted 100 ul of a bacterial stock with 800 ul distilled water, but the sample still needs further dilution

Step 2: You then take 100 ul of the dilution from step 1 and dilute it further with 400 ul of distilled water.

A.) What is the dilution factor after Step 1? (2 points)

B.) What is the final/total dilution factor at the end of Step 2 from the starting stock? (2 points)
