- A 1.2cm diameter glass cuvette is filled with a Cu(NH3)42+ solution that is deep blue. The cuvette is placed into a pre-blanked spectrophotometer. At 620nm, the transmittance is 23%. If the solution has molarity = 0.0133 M and path length of light through the solution = 1.2 cm, what is the value of molar absorptivity at 620 nm?. A 2.50*10–4M solution of a dye has an absorbance of 0.860 when measured in a 1.00 cm cell at 625 nm. Calculate the %Transmittance of the solution. Will the %Transmittance increase or decrease if the concentration of the dye is increased.What is a “Morse potential”? (max. 50 words)

- The drug pentobarbital is a sedative. It was extracted from a urine sample during a particular ultraviolet-visible spectrophotometric forensic analysis procedure. The extraction solvent was evaporated and the residue reconstituted in a small volume of the transparent solvent methanol. The pentobarbital solution thus obtained had a percent transmittance (%T) of 91 at the relevant wavelength of maximum absorbance. If the urine analyte concentration were halved, what would its percent transmittance be? (You may assume that the Beer-Lambert law holds). Can you show all the steps of the solutionThe following are the reasons why instrumental analysis methods are used, except for: a. Narrow concentration ranges may be detected. b. Extreme low sensitivity, with molecule and noise signal detection. c. Separate equipment or facilities for control, data handling, and optimization procedures. d. All of the above1. A 10.0 mL sample of a diluted solution has a transmittance of 25.1%. Determine the connection of this solution. 2. If the diluted solution was prepared from 3.0mL of a concentrated solution, what was the concentration of the concentrated solution?
