Consider the peaks for pentafluorobenzene and benzene in the chromatogram below. The elution time for unretained solute is 1.06 min. The open tubular column is 30.0 m in length and 0.530 mm in diameter, with a layer of stationary phase 3.0 m thick on the inner wall.

(a) Find the adjusted retention times and retention factors for both compounds.
(b) Find the relative retention, α.
(c)Find the unadjusted relative retention,γ .
(d) Measuring w1/2 on the chromatogram, find the number of plates, N1 and N2, and the plate height for these two compounds.
(e) Measuring the width, w, at the baseline on the chromatogram, find the number of plates for these two compounds.
