Could someone please tell me what formula(s) I use to solve this problem> 12. A wild type strain of Pseudomonas was plated on TSA. 0.5ml of a 10-7 dilution resulted in 46 colonies, while 0.1 ml resulted in 203 colonies from the same diluted culture. What was the titre (concentration) of the Pseudomonas stock culture from which the dilution was prepared?
