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...

Lab 5: Additional Dilution Problems You have a stock solution that contains 24 mg/ml of protein. You want to make a set of standards with the following concentrations: 12 mg/ml, 6 mg/ml, 3 mg/ml and 1.5 mg/ml You need a minimum of 500 ul of each standard after all dilutions are completed. Using the technique of serial dilution, explain how you would make your standards by filling in the chart below. Std 4 Std 1 12 Std 2 6 Std...
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of...
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...

If this 2.0 ppm dilution is still measurable, the detection limit for STD-B is less than 2 ppm. You cannot add more than 7 mL to a TT (it will overflow), so for a more dilute sample, you will have to begin with a smaller amount of STD-B. Adjust the pipette to withdraw just 0.10 mL of STD-B, and transfer this to a new TT. Calculate the volume of solvent solution that must be added to 0.10 mL of the...
