Osmotic pressure of the ocean (salinity)

Value 30 Atm
Organism Biosphere
Reference eBook Marine Biology, 1971 Publisher Springer Berlin/Heidelberg, U. Zimmermann and E. Steudle, Effects of potassium concentration and osmotic pressure of sea water on the cell-turgor pressure of Chaetomorpha linum, pp. 132-137 Table - link
Method Value given in table link is p=3.125 MPa. 1Atm=101325Pa therefore p=30.84 Atm
Comments The general equation is: p = iMRT where i is the van 't Hoff factor, M is the molarity, R the gas constant and T absolute temperature.
