b3tty Canada216 Posts February 25 2009 06:26 GMT #1 Assuming that the osmotic pressure of a sample of sea water at 10 C is 22.0 atm, calculate the work required under reversible conditions at this constant temperature to prepare 76 litre of pure water from this sea water. (Take the available volume of sea water as infinite and therefore unchanging in composition as 76 litre of pure water is extracted). Express your answer in Joules. HELP? Not sure what to do.

Hippopotamus 1914 Posts February 25 2009 23:39 GMT #5 You know, I used to say this stuff. But then I realized that there is a net benefit to posting questions about HW on TL. People with huge egos and a conviction that they're the smartest on earth can come and subtly let out some of that feeling by helping someone out with homework. Better in this thread than in a serious discussion.
