1. The wavelength at wich a substance absorbs the most light is called the wevelength max. The metal complex Cu(C2N2H8)2SO4 has a purple (violet) color. What would you guess as the value of wavelength max?
2.If a solution sample has an extinction coefficient of 7.53 L mol^-1 cm^-1, a pathlength of 1.30 cm, and an obsorbance of 0.569, what is the concentration of the solution in molarity?
3. How many grams of Cu(C2N2H8)2SO4 would be needed to make 250.0 ml of 0.00500 M solution?
Please show all work.

Thanks! BEER'S LAW EXPERIMENT S PRE-LAB QUESTIONS Fully answer these questions in your laboratory notebook before coming to lab. work for numerical calculations. 1. The wavelength at which a substance absorbs the most light is called the The metal complex Cu(C,N,H)SO, has a purple (violet) color. What would you guess as the value 2. If a solution sample has an extinction coefficient of 7.53 L mol cm,a pathlength of 1.50 cm, and an absorbance of 0.408, what is the concentration...
Based on table 1, why Lmax shifts towards higher wavelengths when you go from ethylene to b-carotene? Figure 1. violet blue green yellow orange red purple 500 800 nm The greater the degree of conjugation of chromophores the greater the chance that the absorption of light will occur at higher wavelengths. Table 1 illustrates the effect of conjugation (where max gives the wavelength of maximum absorption): # of conjugated double bonds 175 Table 1. Compound Ethylene 1,3-Butadiene 1.3.5-Hexatricne B-Carotene 258...
