Dilutions question. Original Microbial concentration.
16.3 L 7 After 48 hours of Incubation at 37° C you observe the following growth on plate 5: Plate 5 270 colonies 71. What was the original microbial concentration of the Swimming Hole sampled, and how much bacteria was present in the initial sample volume obtained?

Now knowing the MPN value, you decide to do a dilution series in order to figure out the original bacterial concentration of the Swimming Hole, just in case it is not a coliform causing the gastric distress and simply a bacterial overgrowth. You perform the following dilution set: from your 16.3-liter Swimming Hole sample you transfer 10.7 x 10-3 liters into container A which has a volume of 6,250ul, you then transfer 1.7 mL from container A into container B...

You need to calibrate an instrument by creating four ~100 mL standardized stock solutions. The first solution will be 0.195 M copper (II) nitrite. The copper (II) nitrite is both solid and anhydrous. The remaining three solutions will be serial dilutions of factor 1/10 from the first standard stock solution. Lay out a detailed procedure, protocol, method, and/or recipe for exactly how to create these 4 solutions including all necessary calculations and final molarities. Be sure to be specific into...
