Compute free energy required to transfer one mol of water

Question

Problem

Freshwater lakes receive water from the oceans through evaporation by sunlight. Consider the ocean to be made entirely of NaCl of 0.4 M in ionic strength and the lake to be 0.001 M in MgCl₂. Compute the free energy required to transfer 1 mol of pure water from ocean to lake. Assume a constant temperature of 298 K.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
