Question one: Topic Molecular Spectroscopy (16 marks) * unknown = museture - contains salts You were given an unknown mixture that contains two metal salts (A) Co(NO3)2 and (B) Cr(NO3)2 and requested to determine their concentration. The following representative information about the absorbance data were also provided. Measurements were made in a 1.0 cm quartz cells. Pure A (mol/l) 1.5 x 10-1 0 Pure B (mol/l) 0 6 x 102 Abs @510 nm Abs @575 nm 0.714 0.097 0.298 0.757 0.330 Unknown conc in mixture Unknown conc in mixture 0.671 How would you go about calculating the concentration of the two salts?
