Explain the semipermeable membrane to obtain water

Reference no: EM13532776

A reverse osmosis unit is used to obtain drinkable water from a source that contains 0.570 g NaCl per liter. What is the minimum pressure (in torr) that must be applied across the semipermeable membrane to obtain water? Assume room temperature or about 298 K. (Don't forget the van't Hoff factor!)
