A solution contains 0.00750M of
a first compound with an extinction coefficient of 22.4cm−1M−1. A
second compound is added to the solution at a concentration of
0.0260M. The absorbance of the resulting solution is 0.324 with a
path length of 1.00cm. What is the extinction coefficient for the
second compound in the solution? Round the answer to three
significant figures. Give the answer to three significant
figures.

A solution contains 0.032M of a first compound. The absorbance through a path length of 1.00cm is 0.768. A second compound with an extinction coefficient of 15.2cm−1M−1 is added to the solution, and the absorbance increases to 0.940. What is the concentration of the second compound in the solution? Give the answer to three significant figures.
