Ignore All '+' signs while solving. for better visualisation redraw the structure in a paper without the '+' signs. Here '+' are given to maintain the structure as it does not take spaces and the structure was not accurate.

Hi there, some time ago I worked on alcohol separations by Carbowax 1500 packed GC using FID and N2 as carrier. The alcohols are methyl, ethyl and 1-butyl. Somebody told me that there's an equation that relates the %mole to the %area, obviously there's an equation for each alcohol. And I'm going mad trying to find them. So the question is: can you tell me the equations, for god's sake?

Please help me...!!!!!!
