Ocean water typically contains 35 moles of salt ions dissolved in each 1000 moles of water. Assuming that ocean water has the same density as pure water convert this ratio into a molarity and calculate the expected osmotic pressure of ocean water.cean water typically contains 35 moles of salt ions dissolved in each 1000 moles of water.

The commonest way to record salinity is to measure the amount of salt in 1000g of water, so it is referred to as âparts per thousandâ or ppt. Most of the ocean has a salinity of between 34ppt and 36ppt. Some properties of water are changed by having salt in it: 1  Salt makes seawater more dense than freshwater.here are many chemicals in seawater that make it salty. Most of them get there from rivers carrying chemicals dissolved out of rock and soil. The main one is sodium chloride, often just called salt. Most seawater has about 35g (7 teaspoons) of salt in every 1000g (about a litre) of water.
