1. Light is passed through a solution with an optical path length of 2 cm and the absorbance is recorded as 0.40. If light is passed through the same solution at the same wavelength and the optical path length is reduced to 1 cm, what should the absorbance be?

A solution of a dye absorbs light of wavelength 480 nm, and for this absorption; the extinction coefficient is 18600 dm3 mol-1 cm-1. A sample of the dye of unknown concentration is placed in an optical cell of path length 1 cm and the absorbance reading is 0.18. What is the concentration of the solution? 2.0 * 10-6 mol dm-3, 0.26 mol dm-3, 9.7 * 10-6 mol dm-3, 3.0 * 10-5 mol dm-3
