Seawater has a salinity of 3.5%, meaning that if you boil away a kilogram of seawater, when you're finished you'll have 35 g of solids (mostly NaCI) left in the pot. When dissolved, sodium chloride dissociates into separate Na+ and CI-ions. Calculate the osmotic pressure difference between seawater and fresh water. Assume for simplicity that all the dissolved salts in seawater are N aCl.
