In a spectrophotometry experiment, (34.1±0.2)% of the light (=I/Io) was transmitted through the sample. The molar absorptivity, e, of the analyzed was measured separately and determined to be (1.47±0.03)×104M' cm', and the path length of light, b, was (1.00 + 0.01) cm. Determine what is the concentration and the uncertainty in concentration of the analyte, with proper units. Be sure to show your work. In this problem you will need to use Beer's Law.
