A volume V_aq of aqueous solution containing a mass m_A of compound A is extracted with dichloromethane. A volume V_org of dichloromethane is available. The partition coefficient of compound A between dichloromethane and water is denoted by k (defined as the ratio of the concentration of A in dichloromethane to that of A in the aqueous phase. The question is whether it is better to do one extraction with volume V_org of dichloromethane or three extractions each with volume V_org/3 of dichloromethane in order to maximize the mass of compound A transferred to the organic phase.
Using the input data from Table 1, calculate m_AS, the total mass of compound A extracted after a single extraction with volume V_org.
Using the input data from Table 1, calculate m_AT the total mass of compound A extracted after three extractions, each with volume V_org/3
