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.

Absolute (or ideal) salinity is the mass fraction of salts in seawater [17]. In practical terms, salinity is expressed as PSU (practical salinity units) which are based on water temperature and conductivity measurements [17].
