A mixture of benzene, toluene, and methane was injected into a gas chromatograph. Methane gave a sharp spike in 42 seconds, whereas benzene required 251 seconds and toluene eluted in 333 seconds. Ethylbenzene was eluted at 350 seconds. Find its retention factor and the relative retention and unadjusted relative retention time for ethylbenzene and toluene.

A mixture of benzene, toluene, and methane was injected into a gas chromatograph. Methane gave a sharp spike in 42 s, whereas benzene required 251 s and toluene was eluted in 333 s. Find the adjusted retention time and retention factor for each solute.
A student developed a new dye called Dye C. It was analyzed against other dyes using paper chromatography. A solution of 1:1 ethyl acetate:hexane was used as the eluent. The resulting chromatogram is shown in the figure. Determine the retention factor (Rf) values of each spot on dye C. (use 2 decimal places) What other dye/s are present in dye C and what is the dye with least number of pigments?
To quantify the amount of ethanol in a beverage, a technician prepared the first solution which contained 4.90 grams unknown, 1.00 grams acetonitrile, and 4.10 grams water. After the GC analysis which reported the peak areas of 5,742 for ethanol and 3,829 for acetonitrile, the technician added 0.20 grams ethanol to the first solution and ran the GC analysis again. This time, the peak areas of 6,382 for ethanol and 3,709 for acetonitrile for solution 2 were obtained. What was the percent by mass ethanol in the original beverage?
An unknown compound was analyzed by GC with octane (C3H18) and decane (C10H22). The adjusted retention times were 14.6 min for octane, and 31.6 min for decane. Calculate the retention index for the unknown if its adjusted retention time was 21.2 min.

The ethyl acetate (CH3COOC2H5) concentration in an alcoholic solution was determined by diluting a 10.00-mL sample to 100.00 mL. A 20.00-mL aliquot of the diluted solution was refluxed with 40.00 mL of 0.04672 M KOH: ethyl acetate.JPG After cooling, the excess KOH was back-titrated with 3.85 mL of 0.04644 M H2SO4.

A young researcher set out to develop a method for quantifying the polycyclic aromatic hydrocarbon (PAH) content in a contaminated soil sample using open tubular gas chromatography. During the initial stages of method development, the researcher was unable to separate the early eluting compounds, anthracene and naphthalene, with baseline resolution. Select the possible modifications the researcher could make to improve the resolution. use a column with a smaller inner diameter decrease the column length increase the stationary phase thickness increase the temperature choose a different stationary phase
QUESTION 5 In a chromatographic separation using a polar stationary phase and a mobile phase composed of 60% hexane and 40% ethyl acetate, two compounds, benzene (peak A) and toluene (peak B), are eluted. The width of peak A at its base is 1.2 min, the width of peak B at its base is 1.3 min, and the retention time of peak A is 5.2 min and peak B is 3.5 min. What is the resolution (Rs) between these two peaks and is it acceptable? R = 1.36. It is not an acceptable resolution. R = 0.74. It is an acceptable resolution. R = 1.36. It is an acceptable resolution. R = 0.74. It is not an acceptable resolution.
