Imagine a pharmasudical drug that is more 6x more soluble in H_2O than in toluen

Question

Imagine a pharmasudical drug that is more 6x more soluble in H_2O than in toluene at RT. This drug is synthesized in an aqueous solution with high yield (0.01 mole/L) and a byproduct of the reaction is a neuro-toxin (0.0001 mole/L) that is 6x more soluble in toluene than in H_20 at RT. Assuming a multistage equilibrium separation between the synthesis product in the H_20 stream and toluene with an H_20 solution molar flow rate of M_beta =10 mol/min. What flow rate of toluene is necessary to achieve 1000x reduction of the impurity after mixing 10 stages? And what is the concentration of the drug in the resulting H_20 phase?

Explanation / Answer

Please put this in chemical engineering section.
