Yоu аre tаsked with enumerаting the viral lоad оf an unknown sample. You begin your investigation by serially diluting the sample resulting in the following dilutions: 10-2, 10-4, and 10-6. You spread 80µl of each dilution onto a separate nutrient agar plate and incubate for 48 hours. Upon examining the plates for the 10-2 and 10-6 dilutions only. You observe the following results:  10-2: 125 PFU  10-6: 90 PFU  Calculate the phage titer for these two agar plates. Report your final answer in the correct notation and with appropriate units.
