Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? 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 Because absorbance is proportional to the concentration of the analyte, whereas %T is not ANSWER DOWNLOAD EXAMIANS APP
