The effect of internal droplet radius in orders of nanometer on the mole fraction of toluene in each internal droplet, for a system with globule radius of 30 µm, considering the liquid solutions to be either ideal or non-ideal mixtures. The initial numbers of moles is \(3.89\times {10}^{-10}\text{ mol}\) of toluene and \(3.57\times {10}^{-10}\text{ mol}\) of n-heptane, \(1.07\times {10}^{-9}\text{ mol}\) of water, and \(1.5\times {10}^{-9}\text{ mol}\) of n-dodecane. The reservoir temperature and pressures are 298.15 K and 1 atm. The values used for the interfacial tension between the membrane-internal phases is \(39 \, \text{mN} / \text{m}\) and for external-membrane phase is \(53.7\, \text{mN} / \text{m}\).
