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 cannot be measured as accurately as absorbance None of these Because %T is dependant on the power of the incident radiation Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T cannot be measured as accurately as absorbance None of these Because %T is dependant on the power of the incident radiation ANSWER DOWNLOAD EXAMIANS APP
