Plot the osmotic pressures that ought to be developed by solutions of high molecular weight poly$($dimethyl siloxane$)$ in benzene separated from pure benzene by a membrane permeable only to benzene as a function of ${}_2$ for ${}_2=0\mathrm{.}1,0\mathrm{.}3,0\mathrm{.}5,0\mathrm{.}7$ and $0\mathrm{.}9.$ Assume temperature of $25C.$ Also note the following values of ${}_1.$
