Can you fill in the mixed up numbers in this dilution calculation?
Imagine that you create a four-step dilution series, where the amounts of culture passed from one stage to the next and the amount of medium added at each stage are multiples of 10 between 10ml and 100ml each time. In each case there are initially 100,000 cells/ml; the final concentration is given in the diagram as a rounded number.You can input your numbers into this interactive diagram
