UV-Visible spectroscopy is used to determine the content of an analyte in a capsule. Weigh 100.0 mg of the capsule contents (total weight of contents 500 mg), add 2.0 mL of 0.05 M NaOH, filter the flask, and make up to 25.00 mL with NaOH. The measured transmittance of this solution is 33.0%. The analyte standard is prepared by dissolving 10.0 mg of standard in 25.00 mL of 0.05 M NaOH, then taking 10.00 mL of that solution and diluting to a final volume of 50.00 mL where the transmittance is obtained from 44.0%. Calculate the content of the analyte in the capsule.

Iam stuck on how to start this problem. Youo are presented with a sample of freshly squeezed carrot juice and are asked to determine how much beta-carotene is presented in the juice. A beer's Law plots is constructed from the absorbances at 451 nm for six standard solutions of beta-carotene, with concentrations ranging from 0.75-7.5 µM. Linear regressions data: y=0.1431x-0.0078(R2=0.9998) a)The carrot juice is diluted by one-fourth, and the absorbance at 451 nm of this solutions is measured to be 0.676. Based on this information, what is molor concentration of beta-corotene in the original(undilited) sample of carrot juice? b) If the original sample of carrot juice was 312 mL, calculated the mass(g) of beta-carotene presented

An absorbance calibration curve for Zn was fitted to equation A = 0.913×`Zn, ppm`. Flask 1: To the first flask, a 1.00 mL aliquot of the unknown Zn solution was diluted to 100.0 mL in a volumetric flask; the absorption intensity from this sample was measured to be A = 0.204. Flask 2: To a second flask, a 1.00 mL aliquot of the unknown Zn sample and a 1.00 mL aliquot of 10.00 ppm Zn solution were added and diluted to 100.0 mL in a volumetric flask; the absorbance of this sample was measured to be A = 0.294. Calculate the % spike recovery for the analysis and report to the nearest whole number. Hint: A=mC of the type y=mx, so C=A/m %Spike=100%((Cspike-Coriginal)/Cadded)) Cadded can be found from C1 V1=Cadded V2.
