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...

Dilution is a process in which the concentration of a solution is lowered by adding more solvent. Some of the reasons dilutions are performed are to minimize measurement errors when preparing a series of solutions at different concentrations, to save time and laboratory space, and to make more accurate measurements on an analytical balance when the target concentration is very low. The new concentration of a diluted solution can be determined from the following equation, sometimes called the dilution equation,...
please do 5, 6, 7
and also please tell me the dilution factor of tube two (that
is number 8 on a different page)

1) if 5 parts sample is added to 10 parts diluents, what is the dilution that was just made? 2. What is the ratio if 5 parts sample volume is added to 10 parts diluents volume? 3. In a 1 to 3 dilution, what is the dilution FACTOR? 4. In a 1 to 10 dilution, what is the dilution FACTOR? 5. What is the dilution FACTOR if 40 mcL of sample added to 260 mcL of diluent? 6. What is...
How do you find the initial concentration if you are only
given the initial volume and final volume? I have tried using the
V(i) x C(i) =V(f) x C(f) equation but it needs at least 3 figures
so I'm a bit lost right now.

13. A 1/2, fourfold serial dilution was performed. The original concentration of the analyte was 1200 μg/dL. What is the concentration of the analyte in the final tube? 7. Calculate the true analyte value given the following information: Analyte diluted using 10 μL into 90 μL diluent; Diluted analyte value = 85 mg/dL.
