A 500. µl aliquot of a caffeine unknown is diluted to a total volume of 10.00 mL. A calibration curve for caffeine was generated using external standards on the HPLC. The equation of the curve Caffeine Area(mV cm)=1.266C(ppm)+0.029. If the HPLC peak for the diluted unknown has an area of 3.07 mV cm, what is the original caffeine concentration in ppm?

Spectrophotometric Determination of a Metal A 100.00 mL of exactly 250.0 mg/L Cu2+ stock solution was prepared using a 99.95% pure Cu(NO3)2-3H20 (241.60 g/mol). From this stock, a series of standard solutions were prepared by pipetting certain volumes into 100-mL volumetric flasks, followed by adding 2.00 mL of concentrated NH3, and finally diluting to mark with deionized water. Additionally, a blank solution was prepared by using only NH3 and distilled water. Question: Why was NH3 added to each standard solution before diluting with distilled water? What will be the resulting color of the solution and why is this the color that is observed?

A scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The ic results of a preliminary run, which used a solution known to contain 1.37 mg/mL of methyl benzoate (peak A) and 1.51 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 301 and the area of peak B is determined to be 349 measured in arbitrary units by the computer. To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.41 mg/mL is mixed with 1.00 mL of the plant stream material. Analysis of the mixture gave a 10 Time (min) 15 peak area of 499 for peak A and 417 for peak B.
