- calculate the CFU/ml of a urine sample if 84 E. coli colonies were counted on NA when 50 microliters were plated on the NA plate from a 10-6 dilution tubeIf you performed the serial dilution using 0.9ml of tapwater originally and mixed and transferred 0.1 ml each time, what would be your dilution in tube 8?You are given a buffer that is labeled 10x and your instructor asks you to dilute it to 1x in the final tube. If you have a final volume of 100uL in your tube how much of the 10x buffer will you need to add to bring it to 1x? Do you need to add anything else to the tube before using the new solution?
