5. Suppose that in the plate "D" from exercise #3 above you counted 293 colonies. What is the concentration of bacteria in the original sample? Show your rationale and make sure that the result is expressed in "two-significant figures". Do not forget of variables units as showing them in your rationale, such as "colonies" and "CFU/ml" or "CFU/g"

Transcribed Image Text:3. Consider adding 1 g of breakfast burrito into 999 ml of water. Calculate 1,000-fold dilution for
five consecutive tubes. Explain the dilution created for each tube (A, B, C, D, and E) by using a
dilution scheme.
Stir spoon with spoon and use the beaker to remove 10 ml of breakfast
A serial dilution is any dilution in which the concentration decreased by same factor
