Homework Statement
For public health reasons, you are investigating small systems that turn sea water into drinking water. One portable system takes a volume of saltwater and produces two thirds that volume of freshwater with an increased concentration of salt in the other third of the volume. A typical salinity of seawater is 3.5% and its density is 1025 g/liter. To be practical, this system must run on a small solar cell array. Your first step is to calculate the minimum power necessary to produce enough drinking water for a person in an ordinary environment in a reasonable amount of time. Checking your period chart you find, hydrogen has 1 proton, oxygen has 8 protons and 8 neutrons, sodium has 11 protons and 12 neutrons, and chlorine has 17 protons and 18 neutrons.

The Attempt at a Solution
I really want to work through this problem with someone on here. Entropy is the one major topic I feel clueless on and this is pretty much the only sample problem I have to practice with before my final exam this week. If someone could work through this problem with me, it'd be so greatly appreciated. I'm unsure on how to begin it...
