Five grams of Neswonder coffee was subjected to the extraction procedure for caffeine. The caffeine extracted was made up to 25 mL with using a solvent and scanned with an IR spectrophotometer attaining a response y of 0.65. Based on the calibration curve above, calculate the concentration of caffeine in Neswonder in %.

tras 12. A standard stock solution is diluted to generate three working standard solutions containing ethyl acetate (EA) at 50 ppm, 400 ppm, and 800 ppm. An internal standard, n-butanol (nB), is added so its concentration is 1500 ppm in each of the working standard solutions. The solutions are analyzed using GC- FID. The peak area data for the peak corresponding to ethyl acetate from the standard chromatograms 50 ppm (EA area = 5.05, nB area = 124.37) 400 ppm (EA area = 47.98, nB area = 125.31) 800 ppm (EA area = 98.21, nB area = 98.21, nB area = 130.63) The results for the linear regression analysis for the data set using Excel are: m = 0.7065, b = 0.002134 m = 1.4251, b = -0.003901 m = 1.4215, b = -0.003091 m = 0.7015, b = 0.002231
A mixture of three components is separated using paper chromatography, and each component is analyzed using absorption. With standards containing 100 ppm of each component run simultaneously, the following data were obtained: cmpd A, 0.72 absorbance; B, 0.55; C, 0.80. For the unknown mixture, the data obtined when run under identical conditions were as follows: cmpd A, .0.15 absorbance, B, 0.84; C, 0.75. a) Calculate the relative percentage composition of the unknown mixture. b) The distances traveled by the three components were 8.5, 6.3, and 5.5 cm, respectively.
