Assuming that the osmotic pressure of a sample of sea water at 10 C is 25.5 atm, calculate the work required under reversible conditions at this constant temperature to prepare 9 litre of pure water from this sea water. (Take the available volume of sea water as infinite and therefore unchanging in composition as 9 litre of pure water is extracted). Express your answer in Joules.
