A 50 mL sample of soup was found to be contaminated with E. coli. A dilution of the soup was prepared by adding 14 mL of the soup to 20 mL of water. This was then diluted 1/60, and finally 10-3. Then .25 was added in to 2 plates. The first plate had a colony count of 72 and second had 65. To do the dilution series does the 50 need to be added?

The answer is ""

Explanation:

The very first thing we must do is figure out where the plate was really a countable sheet.  By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range.  We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.

We need to calculate its dilution factor for both the second item. Increase for all of this
