What is the final dilution of a sample after 4 successive 1:10 dilutions? what is the dilution factor?
Help! Not sure how to do dilutions! 1. Calculate the serial dilutions using the following diagrams. 5mL 5mL 1mL 25mL 99ml 75mL 45mL 5mL Dilution: 0.1mL 01mL 0.1mL 1.0mL .9mL 9.99ml 99.9mL 2mL Dilution:
Pre-lab L07 Solutions, Concentration and Dilutions (10pts) Name 1. How do you determine the polarity of a compound? 2. How do you predict the solubility of a compound based on its polarity? 3. What is the mass/mass percent concentration of a solution? (Describe in detail or write and equation.) 4. What is the mass/volume percent concentration of a solution? (Describe in detail or write and equation) 5. What is the molarity concentration of a solution? (Describe in detail or write...
dilutions dilutions What are the resulting dilutions? Notice units of measurement. a) b) c) 500 L of serum is diluted to 2.0 mL 50 uL of whole blood is pipetted into 0.95 mL of diluent 500 mL of liquid K is added to 4.5 L of water 7. If 10 uL of urine is added to 90 uL of water, and the resulting solution is brought to a final volume of 0.50 mL with water, what is the final dilution...
I have to do a serial dilution for plating bacteria, and I am given a sample that has been diluted to 10-4 already. I will need to plate the 10-5 and 10-7 dilutions. What will be the steps I will have to do? Note: I cannot use any more tubes/saline outside of what I have been given. Materials: 2 tubes labelled 10-5 and 10-7. 20ml of sterile saline 5 ml of the 10-4 diluted sample. Sterile pipettes
Please show how to do these enumeration questions by showing the work. What is the dilution factor if you add 625 µL of culture to 4.375 mL of dilution medium? You count the 10-3 dilution of a yeast suspension using the 1/25 mm2 boxes : you find 45 cells in box 1, 15 cells in box 2, 42 cells in box 3, 23 cells in box 4, and 26 cells in box 5. a) What is the original concentration of...
You need to perform a 5 x 10-6 dilution. Give a detailed scheme of how you could carry out this dilution using serial dilutions similar to those you performed in class.
Molarity/Serial Dilution 1. What is the molar mass of (NH2)2NO3? 2. If I have 122g of (NH2)2NO3. how many moles? 3. I dissolve 112.0 grams of Na,Co, into 150 mL of water what is the molarity of the solution? 4. I have a 2.0 M of HCl, if I need to make a 2.5 liters of 0.1 M HCl how many milliliters of 2.0 M HCl will I need?
Prepare at least 6 dilutions of the protein standard, with concentrations of 4, 8, 12, 16, 20, and 24 µg/ml. Do this by diluting pre-calculated volumes of the BSA standard (2 mg/ml) into volumes of distilled water, which results in a final volume of 1.0 ml. Please show calculations for all 6 dilutions.
