F = 0.0966 After establishing the response factor of the instrument, the researcher collected 8.45 g of spinach, homogenized the sample, and extracted the DDT using an established method, producing a 2.45 mL solution containing an unknown amount of extracted DDT. The researcher then prepared a sample for analysis that contained 0.750 mL of the unknown DDT solution and 1.25 mL of 11.94 mg/L chloroform, which was diluted to a final volume of 25.00 mL. The sample was analyzed using GCMS, producing peak areas of 6439 and 14333 for the DDT and chloroform, respectively. Calculate the amount of DDT in the spinach sample. Express the final answer as milligrams of DDT per gram of spinach. amount of DDT: mg DDT /g spinach

1) Calculate the total hardness for the first sample (Sample Volume,V : 50 mL,Volume of EDTA titrant used for the sample, A:9.6 mL) 2)Calculate the calcium and magnesium concentrations for the first sample in the video in meq/L and mg CaCO3/L.(Sample Volume= 50 mL, Magnesium hardness titrant volume = 0 mL, Calcium hardness titrant volume:2,6 mL) 3)Assuming the pH and alkalinity of the first sample in the video are 7.5 and 100 mg CaCO3/L, respectively, calculate the temporary and permanent hardness values for this sample 4How much CaCL2 in meq/L should be added to the sample to equalize calcium and magnesium hardness? Which hardness level (soft, medium, hard, very hard) does the sample belong to after this addition?
The write-up says “A C18-silica column is used in this experiment, a 0.46 x 15 cm column with 5-µm particles. Equilibrate the column with 20 empty column volumes of 0.010 M phosphate buffer (pH 7.2) at a flow rate of 1.2 mL/min before beginning chromatography.” Show the calculation for how much mobile phase you would use (volume) and how long it will take to equilibrate the column.
Next, 2.00 mL of 9.63 mM S was added to 10.00 mL of a solution of unknown concentration of X, and the mixture was diluted to 25.0mL. Chromatographic analysis of this solution produced peak areas of 4822 for X and 4099 for S. What was the concentration of 5 (in mM) of the 25.0mL solution?
When the soft drink Jolt is used in place of Coke in the HPLC experiment, the concentration of caffeine in the injected sample is found to be 5.9 x 10- M. What peak area corresponds to this concentration? Explain how you came up with your answer.
Based on TLC, how can you tell if the reaction is complete and what is the relevvance of the multiple marks in the lanes of the tlc? PROCEDURE To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture wasgently stirred to ensure complete mixing.Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentlestirring. The pH of the resulting reaction mixture was determined and adjusted to >10by dropwise addition of 10% sodium hydroxide. The reaction mixture was then partiallysubmerged in a 65 °C water bath2 and the progress of the reaction was periodicallymonitored by TLC analysis.Once TLC analysis indicated that the reaction was complete, the reaction mixture wascooled to approximately room temperature, and then chilled in an ice-water bath. Theresulting precipitate was collected by…
