A) calculate the osmotic pressure difference between seawater and fresh water. for simplicity, assume thatall the dissolved salts in seawater are nacl.
b) reverse osmosis occurs when you apply a pressure difference greater than the osmotic pressure to asolution separated from a pure solvent by a membrane permeable only to the solvent. in this process, thesolvent flows out of the solution and this can be used to desalinate sea water. use your result from part (a)to find the minimum work required to desalinate one liter of water.
c) it is also possible to desalinate water by evaporation. the water vapor is recondensed and the salt is leftbehind. compare your result from part (b) with the amount of heat that would be required to evaporate aliter of water. assume that the water starts at a temperature of 300k and the latent heat of vaporization at apressure of one atmosphere is 40.7kj/mol. compare your result with that of part (b)
