1. Carbon monoxide (CO) can be determined at trace levels using IR absorption spectrophotometry. Using a 100.0-cm pathlength gas cell, a standard containing 10.0 ppm CO gave an absorbance of 0.050 at 2170 cm-1. Calculate the concentration (ppm) of a gas sample, analyzed using the same gas cell, which gives an absorbance of 0.005 at the same wavenumber. Assume the system obeys Beer's Law over the concentration range investigated.
