1,8-Cineole is a predominant terpene found in cranberries. The concentration of 1,8-cineole in cranberries was determined using gas chromatography. A 5.00 g sample of freeze-dried cranberry powder was added to 10.0 mL waterto form a cranberry extract. The extract was filtered. A 1.00 mL aliquot was added to a 25 ml volumetric along with a known amount of internal standard (d-14 cymene) and diluted to volume with water. Standards were spiked with afixed amount of d-14 cymene as internal standard. The following data was obtained:1,8-Cineole (ug/mL); 1,8-Cineole (peak area); d-14 cymene (peak area)10.0; 1260; 188015.0; 1865; 185020.0; 2520; 185550.0; 6280; 1865Sample; 1976; 1840What is the concentration of 1,8-cineole in ug per gram of cranberry?O 398 ug/gO 159 ug/gO 674 ug/gO 796 ug/gO 15.9 ug/g

6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question: Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles). Calculate the percent yield of cyclohexene obtained.

20 tablets containing the dibasic drug ethambutol hydrochloride (MW 277.2 g/mol) were powdered. 0.3354 g of tablet powder was dissolved in 10 mL of 2 M sodium hydroxide and was extracted with 5 x 25 mL quantities of chloroform. The combined extracts were evaporated and the residue was dissolved in 100 mL of anhydrous acetic acid. Non-aqueous titration was carried out using 1-naphtholbenzein solution as indicator and 0.1014 M acetous perchloric acid. Volume of acetous perchloric acid required = 14.2 mL, weight of 20 tablets = 3.367 g, state content of ethambutol hydrochloride per tablet = 100 mg. Calculate the % of stated content in the tablets.
