A 108 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is plated on solid media, and 264 colonies of bacteria grow on the plate. Assuming each colony came from a single bacterium, how many bacteria are in a single mL of the original culture? Express your answer to two decimal places using exponential notation. • Since only 0.1 mL is put on the plate, this counts as an extra dilution!!! • Any time less than 1 mL is transfered, a dilution is being performed. • Any time more than 1 mL is transfered, a concentration is being performed.
