Table 1: Solute concentration in the organic phase as a function of total solute mass added in the system (extraction vessel)

(a) Determine the apparent volume of distribution of the compound in each phase and the partition coefficient (b) What is the extraction efficiency in the organic solvent? (c) How much compound must be added in the system to achieve an extractant concentration of 2 g/L in the organic solvent? (d) What volume of the organic solvent must be used to extract 99.0 % of the solute?
