A solute $[$ISITSUMMERYET$]$ is in equilibrium in two partially Immiscible liquid phases $($Fluid I $($non aqueous$)=200$mol and Fluid $2($aqueous$)=300$mol $).$ This is a batch process. We know $2$mol of solute has been added in total and the distribution coefficient KistTSUMMERYET$($nonaq$/$aq$)=53.$ If both solutions are at atmospheric pressure and $25C,$

a$.$ If $2$mol of the drug dissolved in $300$mol of fluid $($Aqueous$).$ Calculate the mole fraction of the drug in the aqueous solution.

b$.$ Now we mix this solute in an aqueous fluid, and find the mole fractions in both fluids. Write an expression relating to the liquid mol fractions.

c$.$ Calculate the liquid mole fractions of solute in Fluid I and Fluid II

d$.$ Calculate the percent extracted from the aqueous phase.
