Step 1
This means that the final volume of the diluted solution will be 1/100th of the original volume. So, if we want to make 100 mL of a 1/100 dilution, we need to divide 100 mL by 100. 100 mL / 100 = 1 mL Show more…

Question 2 9 pts Fill in the table below with your data from the experiment: Be aware the table is per mL! You counted how many were in a 0.5 (half mL) sample but the table is asking for how many in 1.0 mL. ONLY RECORD THE NUMBER. DO NOT INCLUDE ANY WORDS OR TEXT OF ANY KIND. i.e. 46 (JUST THE NUMBER) NOT 46/mL, NOT 46 cells/mL, NOT 46 cells. I've filled in the data for the 0 time point for you :) caudatum P aurelia alone, P caudatum P aurelia mixed; Day alone, cells/mL cells/mL mixed, cells/mL cells/mL 10 12 14 16

Plating 0.1 mL of a sample diluted by a factor of 10^(-3) produced 43 colonies. What was the original concentration (OCD) in the undiluted sample? 4.3x10^-5 CFU/mL 4.3x10^-4 CFU/mL 4.3x10^5 CFU/mL 4.3x10^4 CFU/mL
