Compund AFK has a maximum absorbance of 650 nm. Its molar absorptivity at 650 is 8400 M−1cm−1 and the path length is 1 cm. Using a spectrophotometer, determine the concentration of Compound AFK it is absorbance at 650 nm is 0.700 ? 8.33x10-5 mol/L 1.20 x104 mol/L 1.08 x10-3 mol/L 7.74 x10-2 mol/L
When we perform Bradford Assay to measure protein concentration, the spectrophotometer is set 595 nm because: a. the excitation peak of Coomassie Blue is best observed at 595 nm b. when Coomassie Blue binds to proteins, its maximum absorbance shifts to 595 nm c. the reducing effects of Coomassie Blue shifts the protein's maximum absorbance to 595 nm d. myoglobin is best observed at 595 nm
A sample of adenosine triphosphate (ATP) (MW 507, e 5 14,700 M-1cm-1 at 257 nm) is dissolved in 5.0 mL of buffer. A 250-mL aliquot is removed and placed in a 1 cm cuvette with sufficient buffer to give a total volume of 2.0 mL. The absorbance of the sample at 257 nm is 1.15. Calculate the weight of ATP in the original 5.0 mL sample.

10. a. Light at 278 nm passes through protein RNase A with optical path length is 1μm and the concentration of protein RNase A is 0.5 M. If the absorbance is 0.5, what is the absorptivity in M-1 cm-1? b) What is the corresponding transmittance?
50 uL of an aqueous sample of double-stranded DNA is dissolved in 950uL of water. This diluted solution has a maximal absorbance of 0.326 at 260 nm. What isthe concentration of the original (more concentrated) DNA sample, expressed in ug/ul? I would like to know the process of this question. And I was wondering as well if the total diluted volume would be 950ul + 50ul = 1000ul

A specific steroid has a λmax of 249 nm and a molar absorptivity ε of 11,500 L mol−1 cm–1. What is the concentration of the compound in a solution whose absorbance at 249 nm is A = 0.050 with a sample pathlength of 1.00 cm?
At 21 °C, a solution of 12 mL each of 0.00200 M Fe3+ and 0.001000 M SCN- was mixed and brought to 25.0 mL with 0.1 M HNO3. The absorbance at 450 nm was measured to be 0.350 (A450 = 0.350). This solution was then heated to 45 °C and the absorbance at 450 nm was measured to be 0.142 (A450= 0.142). Is the reaction: Fe3+(aq) + SCN -(aq) → FeSCN2+(aq) exothermic or endothermic? Explain.
