NEED HELP WITH B) C) D) E) F) and G) that apply to the spectra below. OTHER ANSWERS ARE THERE TO SUPPLEMENT Thank you! 5. Using the GC mentioned in question 4 and the values listed on the chromatogram for the height and width (at half height) of each peak, calculate the percent composition for each product (A, B and C). Be sure to show your work. Area of peak A = 125 x 8 = 1000mm2 Area of peak...
