Question

Calculate percent composition for both F1and F3. Calculate mass if cyclohexane in F1 and percent recovery of cyclohexane based on F1. Calculate the mass of toluene in F3 and the percent recovery of toluene based on F3. The original weight of the vials when empty is:
           F1: 25.503g
           F2: 27.050g
           F3: 25.138g
the weight of the empty round bottom flask is:
             17.784g

Explanation / Answer

after distillation wt of contents = 26.134-25.503 = .631 g

Based on GC anlaysis fraction of cyclohexane in distilled F1= (2643.45+1371.78)/4233.63

=0.95

wt of cyclohexane in F1 = .95 * .631 = 0.6

silmilarly wt of contents in F3= 26.04-25.183 = 0.857 g

fraction of toluene from GC analysis= 1125.99/4813.05 = 0.24

wt of toluene in F3= 0.24* .857 = 0.205 g
