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 74.0 bar is applied to seawater, what will be the final concentration of the seawater at 20 C when reverse osmosis stops?

Assuming that seawater has a total ion concentration (also known as colligative molarity) of 1.10 Mc, calculate how many liters of seawater are needed to produce 83.8 L of fresh water at 20 C with an applied pressure of 74.0 bar.

concentration: _________ Mc

Volume: ________ L
