The peak integrations of a chromatogram resulting from a GC analysis of a mixturecontaining component X and component Y (of a fractional distillation) shows thefollowing data:Component X - Area = 64.3 sq unitsComponent Y - Area = 156.5 sq unitsWhat was the percentage composition of the compounds X & Y in the mixture?X= 39.1%, Y= 60.9%X= 29.1%, Y= 70.9%X= 48.1%, Y= 51.9%X= 70.9%, Y= 29.1% 5.20 g of tea leaves were used for the extraction of caffeine in a laboratory experiment, If the mass of crude caffeine obtained and the mass of pure caffeine recovered after recrystallization are 0.166 gand 0.082 g respectively, what is the percentage yield of pure caffeine from the tea leaves?O 2.10%O 2.30%O 1.58%O 3.62%

Area under the curve of GC is correspond to mass of that component.

A student performed chromatography on a mixture of benzoic acid (C6H5CO₂H), acetophenone (C6H5C(O)CH3) and styrene (C6H5CHCH₂). She used alumina (Al₂O3) as the stationary phase and a 9 : 1 mixture of hexane : ethyl ethanoate as the mobile phase. Rank the order in which the compounds moved, from fastest to slowest. benzoic acid acetophenone styrene

A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.
An HPLC method was developed for the separation and determination of ibuprofen in blood samples.
