A pure bacterial culture of unknown concentration was diluted to determine the concentration of viable bacteria in the original culture. Serial dilutions were performed as 1. diagrammed below. Each dilution tube contained 400 µul of diluent and 100 µl was transferred into each tube. TSA plates were inoculated with 100 µul from the last three dilution tubes. a. What is the dilution between each tube shown in the diagram below? Express your answer as a ratio. b. What is the total dilution of tube number 5? Express your answer as a ratio. c. What is the concentration of viable bacteria in the original culture? Express your
