Question 17 of 20
In reverse osmosis, water flows out of a salt solution until the osmotic
pressure of the solution equals the applied pressure. Assume
seawater has a colligative molarity of 1.10 M, and you want to use
reverse osmosis to produce freshwater from the seawater.
Calculate the volume of seawater (in liters) required to produce 10.0
liters of freshwater when a pressure of 65 atm is applied to the
seawater at 25°C. The ideal gas constant is 0.08205 L·atm/mol K.
