Interpretation:
The percent transmittance and absorbance for the given sample are to be calculated from the given data.
Concept introduction:
UV–vis spectroscopy uses light from the UV and visible regions of the spectrum. These wavelengths range from
At each wavelength, the intensity of light that reaches the detector (
The percent transmittance is converted to the corresponding absorbance by using the following equation:
Answer to Problem 15.1P
The calculated percent transmittance for the given sample is
The calculated absorbance for the given sample is
Explanation of Solution
It is given that the intensity of the radiation from the source (
The percent transmittance (
Thus, by putting all given values we get
Thus, the calculated percent transmittance for the given sample is
The percent transmittance is converted to the corresponding absorbance by using the following equation:
Thus, the calculated absorbance for the given sample is
The percent transmittance and absorbance for the given sample are calculated from the given data by using corresponding equations.
