1. Serial dilution Questions: a) (5 pts) Suppose you begin with stock solution of dye that has a concentration of 350.0 mg/L and do the following set of serial dilutions on it: 5.00 mL of stock diluted to a total volume (TV) of 500.00 mL (Dilution 1); 2.00 mL of Dilution 1 is then diluted to a TV of 250.00 mL (Dilution 2); finally, 1.00 mL of Dilution 2 is then diluted to a total volume of 100.00 mL. Calculate...
You only have 150 pl stock solution that contains 100 mgml of protein. You want to make a set of standards with the concentrations shown below. You need a minimum of 500 l of each standard left after you have finished all your dilutions. Using the technique of serial dilution, explain how you would make your standards by filling in the chart below include the final dilution of the standard as compared to the original stock concentration and the final...
The standard concentration of the antibiotic Vancomycin is 6.20 mg/dl. It is diluted 1:10. Then 1.0 ml of the first dilution is added to 4.0 ml of diluent? What is the final concentration of the antibiotic in this solution?
