When observing your plaque count results, suppose that you count 89 plaques on the plate prepared using the phage suspension with 1000 total dilution factor. how would you calculate the concentration (pfu/ml) of the original phage suspension? (refer to the lab manual to recall the procedure you used to prepare your plaque count plates.) show your work.
