A student was given an unknown mixture and was asked to determine its composition by thin layer chromatography using silica gel as a stationary phase and a 50:50 mixture of ethyl acetate:petroleum ether as the mobile phase. The unknown mixture could be composed of compounds A-E. The student ran one TLC plate containing compounds A-E, and a second TLC plate of their unknown mixture. Calculate the R, values for all components identified in these TLC analyses and use this data to determine the composition of the unknown mixture. -+-+-+-+-+- ABCDE Unk
