Step by step
Solved in 2 steps with 1 images
- A solution has a measured absorbance value of 0.120. What percent of the light entering the solution will pass through? (i.e. What is the percent transmittance of the solution?) Answer: Percent Transmittance (%T) =IR Spec question: https://webbook.nist.gov/cgi/cbook.cgi?ID=B6007500&Mask=80 The spec is chloroform, deutero. I don't know what the peaks are around 3200 cm-1, 3000 cm-1 and 2300 cm-1.Give reason for: 3- A sample must be bombarded with electrons in mass spectrophotometry. 4- X-axis in IR spectrum is wave number in cm-1 instead of wave length. *Short answer*
- Which of the following relationships between absorbance and %Transmittance are incorrect? correct incorrect A = 2 - log10%T. correct incorrect A = log101000/%T. correct incorrect A = 1 - log10 1/%T.A student prepares a solution of his dye and measures its absorbance using a 1 cm cuvette. The absorbance is 0.37 and the concentration of the solution is 2.0 * 10-5 M.
