Question: For a microbiology experiment, you need a bacterial culture of 5.4 × 106 cells/ml. You think your suspension is at the right concentration, but want to further verify by a 10-fold serial dilution and plate counting. What three dilutions should you use assuming your original estimate is correct (to get countable plates)? You are going to plate 0.1 ml solution for each of the three dilutions.
