Yоu аre tаsked with enumerаting the micrоbial lоad of an unknown sample. You begin your investigation by serially diluting the sample resulting in the following dilutions: 10-2, 10-3, and 10-4. You spread 100µl of each dilution onto a separate nutrient agar plate and incubate for 48 hours. Upon examining the plates for the 10-2 and 10-4 dilutions only. You observe the following results: 10-2: 220 CFU 10-4: 60 CFU Calculate the viable titer for these two agar plates. Report your final answer in the correct notation and with appropriate units.
