Problem 2. A vapor stream leaves the top tray of a distillation column and enters a partial condenser. It is desired to operate the condenser so that \( 75 \mathrm{~mole} \% \) of the total stream is liquified ( L ). If the liquid and vapor streams leaving the condenser are at \( 80^{\circ} \mathrm{F} \), what is the pressure in the condenser? The stream has the following analysis:
