Spectroscopy Molar absorbtivity is the measure of the amount of light absorbed per unit concentration None of these amount of light absorbed per unit length amount of light reflected and absorbed per unit concentration amount of light absorbed per unit concentration None of these amount of light absorbed per unit length amount of light reflected and absorbed per unit concentration ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance None of these Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance None of these ANSWER DOWNLOAD EXAMIANS APP
