6.) 0.1ml of culture was diluted in 9.9ml of sterile water. This is mixed well and further diluted by 2 successive 1/10 dilutions followed by 1/100 dilution. An aliquot of 0.1mL of 1/100 dilution was spread on a plate of nutrient agar. After incubation, 55 colonies were present on this plate. What was the number of colony-forming units /ml of the original culture?
