Q3 We want to measure the concentration of a molecule in water that absorbs green light. When a sample solution is illuminated with a green laser from one side of the cuvette we measure green intensity that leaves the cuvette on the opposite side with a detector. 1. What is intensity? 2. The ratio of the intensity of illumination entering the cuvette relative to the intensity that is detected by the detector we obtain 1.2 which can be expressed with transmittance. What is the value of transmittance here? 3. What is the value of absorbance?

You are measuring the concentration of an unknown protein sample, and the absorbance at 595 nm (or A595) of your unknown is greater than that of the highest-concentration standard solution. It is not advisable to simply extrapolate the line of the standard curve to calculate the concentration of the unknown In this scenario, what would be the best strategy to measure the concentration of your unknown (instead of extrapolating from the standard curve)?
Many ions form colored solutions when dissolved in water. For example, aqueous Cu2+ solutions are light blue and aqueous Ni2+ solutions look light green. These metals in particularare often found in stainless steel. Would you expect their presence in your samples to interfere in the spectrophotometric analysis of permanganate at 525 nm? Why or why not? I think the answer is that I would expect the Cu2+ in my samples to interfere but not Ni2+ because the Ni2+ is green, signifying a higher wave length that the spectrometer wouldn't be able to pick up on because it was only set to 525 (blue-ish) where as the green is 530-ish. I just want to make sure thanks!
Solutions that contain the FeSCN2+ ion are blood red (you will see this at the end of the second quarter of lab). Consider the regions of the visible spectrum in which the compound should absorb light and prepare a rough sketch of absorbance vs. wavelength for each solution. Label λ max on the graph. (Is this question asking for the graph of my data at the end)

In determining the amount of copper and the identity of the copper compound in the unknown sample, a 100-mL solution containing 120.8 mg of the sample was initially prepared. Then, 5.00 mL of this solution was pipetted and diluted with deionized water in another 100-mL volumetric flask. The absorbance of this diluted solution was determined three times at the analytical wavelength. The concentration of Cu is 12.678 mg/L, what is the mass of Cu in the analyzed solution and the mass of Cu in the unknown sample?

The nickel level in a soil sample was determined using AAS. A 3.0 g sample was dissolved in acid and then diluted to a total volume of 100.0 mL. The absorbance of this solution determined at a wavelength of 232 nm, was found to be0.3. Several standard solutions were tested under the same conditions and a calibration curve shown below was obtained. Calculate the mass of nickel in mg.
