A reaction of benzene [ 1.5 g ] with 1-chloropropane [1.5 g ] in the presence of AlCl3 yields [1.1 g] product which was subjected to GC analysis equipped with a thermal conductor detector (TCD). The chromatogram obtained shows two peaks identified as n-propyl benzene [area = 67 mm2 Wf -1.09] and isopropyl benzene [area = 105 mm2 Wf -1.06].

Calculate the amount in grams of isopropyl benzene component.
