Homework Answers
Dilution = initial volume / final volume
Final volume = initial volume + volume of diluent
Dilution = 10^-1
Initial volume = 3 mL
10^-1 = 3 / final volume
Final volume = 3 / 10^-1 = 30 mL
30 = 3 + volume of diluent
Volume of diluent = 30 - 3 = 27 mL
So, to 3 mL of sample, add 27 mL of diluent.
Please rate high.

A bacterial sample has a concentration of 2 x106 CFUlml. Show a scheme of dilutions to obtain 30-300 colonies on a plate. Your scheme should contain the volume of diluent (sterile water), volume of sample transferred each time, the concentration of bacteria (CFU/mL) in each dilution. You can assume you are plating 1 mL of the dilution on plates of nutrient agar. See Figure 1 in protocol 10. Dilution factor in single transfer (change x and y to numbers 10...
