a) In reverse osmosis, water flows out of a salt solution until the osmotic pressure of the solution equals the applied pressure. If a pressure of 65.0 bar is applied to seawater, what will be the final concentration of the seawater at 20 °C when reverse osmosis stops?
b) Assuming that seawater has a total ion concentration (a.k.a colligative molarity) of 1.10 Mc, calculate how many liters of seawater are needed to produce 25.9 L of fresh water at 20 °C with an applied pressure of 65.0 bar.
