If either of your water sample plates had a lawn or too many colonies to count, what might you have done, without reducing the volume of liquid you put on the plate, so that you had ended with a countable number of colonies? What does the presence, or absence, of coliforms indicate about your water sample?

1. What is the dilution if 0.1 mL of broth is transferred to 4.5 mL of water? 2. If the dilution is the same in the previous question, you have made 1 plate, and you know that there are 368 colony-forming units per mL in your agar pour, how many colonies would you expect to see on your pour plate? 3. Reference to the previous question. Should you select the plate that you made if you needed to calculate the number of colony-forming units per mL in your original sample? Why or why not?
