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.

In the open ocean the range of salinity is generally from 32 psu to 37 psu. Along with temperature, it is a major factor in contributing to changes in the density of seawater and therefore ocean circulation. Salinity is the key to understanding the global water cycle. 97% of the Earth's free water resides in the oceans. The water cycle is dominated by precipitation and evaporation.
