(a) What is the molar absorptivity of compound Z at 295 nm and 348nm, given the absorption spectrum shown in Fig.22-14 (which was obtained using a UV-Vis spectrophotometer and a 1mM solution of compound Z in a sample cell with a path length of 1 cm)? (b) Now you have decided to make quantitative measurement of the level of compound Z in different solutions. Based on the above spectrum, which wavelength will you use for your measurements? Give two reasons why this is the optimum wavelength.
