For the gas chromatographic determination of ethanol in Joy Daddy Bitters, a number of standard solutions of ethanol are prepared and injected. The peak heights of the chromatograms are measured. A 1.230 g sample of the bitters sample is diluted to 100 ml with distilled water, and 1 µl of the diluted sample is injected into the GC. From the following data, calculate the percent weight by weight (% w/w) of ethanol in the bitters sample. Concentration of Ethanol (mg ml?¹) Peak Height (cm) Ethanol 0.200 3.15 0.500 7.55 1.000 16.00 1.500 21.95 Diluted Bitters 9.25
