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 water to 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 a fixed 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; 1880 15.0; 1865; 1850 20.0; 2520; 1855 50.0; 6280; 1865 Sample; 1976; 1840 What is the concentration of 1,8-cineole in ug per gram of cranberry? O 398 ug/g O 159 ug/g O 674 ug/g O 796 ug'g O 15.9 pg'g
