You are a microbiology lab technician and you need to quantify
the viable cell concentration in your stock culture before
beginning an experiment. Since you do not know the range, you
perform a serial dilution over several orders of magnitude. You use
the pour plate method and plate 1 ml for each dilution level, in
duplicate. Give the most accurate value for the number of viable
cells in the original stock culture, in CFU / ml. Just enter a
number,...
