To finish the technique, let's imagine we count the cells in tube 5 and find 50 total cells, right in the desired 30 to 300 zone in order to determine how many cells we started with in our original culture, all you need to do is multiply the cell count by the total dilution: 50 x 100,000 = 5,000,000 bacterial cells in our original 10 ml sample.
