A particular substance absorbs very strongly at 620 nm. At a concentration of 0.100 M, this substance has an absorbance of 0.835 at 620 nm. Assuming that the path length is 1 cm, calculate the value of the molar absorptivity coefficient, ε. What would be the absorbance (at 620 nm) of a solution of the same substance with a concentration of 0.140 M using the same path length?
