so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...

Serial dilution problem You have a stock of 5% SDS. You take some of that stock and dilute it 4-fold in tube #1. the tubes hold 1.5ml. give an example of how much 5% stock and how much water you would use to make 4 fold dilution - volume of 5% stock ? - volume of water? - How much volume transferred? - if you took a sample out of tube 2 and did another 4 fold dilution, what concentration...

Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...
