Acetic acid is to be removed from its aqueous solution into 1-heptanol. Water and 1-heptanol are immiscible. Calculate the number of stages required for 54.7% removal of acetic acid. Assume that the operating line and the equilibrium line are linear and parallel; pure 1-heptanol is used for extraction.
