Chapter 4, Problem 14P

Convert the accompanying transmittance data to absorbances: (a) 25.5% (b) 32.8% (c) 0.085

the transmittance concentration pairs could have been used to determine a calibration curve. state at least one important problem associated with such a calibration curve

Convert the following absorbance to transmittance. a. 0.283     b.   0.625

The following are the reasons why instrumental analysis methods are used, except for:   a. Narrow concentration ranges may be detected. b. Extreme low sensitivity, with molecule and noise signal detection. c. Separate equipment or facilities for control, data handling, and optimization procedures. d. All of the above
