A UV-visible spectrometry cuvette has erosions on one of the 2 faces through which the radiation passes. How will this affect the measured absorbance?(A). Yes, errors will be obtained due to excess(B). Yes, errors will be obtained due to defect(C). Yes, and the error will be due to excess if the eroded face is the one through which the radiation enters and due to defect if the eroded face is the one through which the radiation exits(D). Yes, and the error will be due to defect if the eroded face is the one through which the radiation enters and due to excess if the eroded face is the one through which the radiation exits

A)What absorbance value corresponds to 80% transmittance? B)What is the new % transmittance value if the absorbance value in A increases by 0.250?

What is the concentration of a sample that transmits 70% signal at a certain wavelength upon analysis? The molar absorptivity is 2.0 and the cuvette used has a width of 1.0 cm.  Additionally, (a) What is the absorbance of the sample at this wavelength? b) And what is the fraction of light that would be transmitted by the sample if the concentration is increased three times?

What is the % transmittance when the absorbance is 1.67

1) What is the % transmittance of a solution that has an absorbance, A of 0.598 ? %T = ?

state if true or false 1. Prior to a fixed point or wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample. 2. The purpose of a diffraction grating is the same as that of a prism. 3. In any UV-VIS spectrophotometer, the light is filtered first to a single wavelength or narrow range before it hits the sample 4. In any UV-VIS spectrophotometer setup, the detector always comes right after the sample container. 5. It is necessary to set the blank before each reading even if the only difference between the sample solutions is the amount of analyte. 6. Prior to a fixed point/wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample.

. Express the following absorbance in terms of percent transmittance  a) 0.0356 b) 0.895 c) 0.379

12) If gloves are not worn when handling the cuvette in a spectrophotometry xperiment, how would this affect the absorbance reading (higher, or lower, or same) and ow would it make the concentration look, higher or lower?

A student calibrated the mini-spectrophotometer with a blank solution, and then went to check their solution. They got a fingerprint on the cuvette while filling it. Because of this, the expected reading for the absorbance would be too high which would cause the calculated value of K, to be too high

What absorbance corresponds to 99% transmittance? To 0.10% transmittance?
