Q5) A student is tasked to determine the number of moles of H2SO4 (aq) in a 200 ml of an unknown solution. The student prepares a series of solutions with known concentrations of H2SO4 (ag) and measures the absorbance of each at an appropriate wavelength. These data are used to construct the calibration plot shown below. 1.00 0.80- 0.60 - 0.40- 0.20- 0.00- 3 x 10-4 6 x 10-4 Concentration (mol/L) If the absorbance of the unknown solution is 0.70, how many moles of H2SO4 (aq) does the 200 ml sample contain? AbsorbanceIn the technique of high performance liquid chromatography (HPLC) the peak area response for a particular analyte is directly proportional to concentration Analgesic tablets typically consist of aspirin and caffeine as the active ingredients, the remainder made up of inert binding material. The concentrations of aspirin and caffeine may be routinely monitored using HPLC, whereby the peak areas obtained from a solution of the tablet are compared with those obtained from standard solutions of the analytes. In an analysis to determine the concentration of caffeine in such a tablet, the following data were recorded: Solutions Analysed: Tablet Sample: Mass of tablet (dissolved in 250 cm methano): 0.523 g Caffeine Standard: Mass of caffeine (diessolved in 500 cm methanol) 0.105 g HPLC results: Solution Peak Area (catfeine) 1.
