Jack, a new MLT at Cape Fear Hospital was given the following information from a patient's urine sample which had been tested for the presence of S. aureus. The urine contained 6.4 x 107 CFU/ml S. aureus, the plate dilution was 10, and the sample had been taken from the 10s dilution tube. Calculate the number of bacterial colonies which must have been counted on the plate and what volume of the sample in ul that was actually plated to give the above results. PS, both of these values can be calculated. Express answers in scientific notation.
