. A sample of cobalt is to be determined using absorption spectrum analysis. A 0.286 g sampleof a cobalt ore is crushed and digested in 1M HNO3. The stock solution is then diluted to 250.0mL in a volumetric flask (assuming the solution has a density = 1.00 g/mL). The analysis thenproceeds as follows: Sample Solution Std Co solution (11.2 ppm) Final Volume Transmittance 15.0 mL 0.00 mL 100.0 mL 54.1% 15.0 mL 5.00 mL 100.0 mL 19.9%Calculate the percent cobalt in the original ore sample.

A solution sample, in a 0.50 cm cuvette, exhibits an absorbance of A = 0.84 at lamdamax= 230 nm. Calculate the concentration of the solution if the molar absorption coefficient of the compound at 230 nm is 14 mol–1 dm3 cm–1.
How do I solve for [FeSCN2+] heres the formula they provided me and my data but I would like steps on how to solve it and what data I should be using to solve for it u can use any fake numbers you need to help me understand ! I'm confused only by the absorbance part , what number am I using for the absorbance? Is it Fe3+ added to ScN- absorbance values ? also e = 202 and L = 1.0
