Composition of seawater pdf

Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na ) and chloride (Cl ) ions). The average density at the surface is 1.025 kg/L. Seawater is denser tha… http://ocean.stanford.edu/courses/bomc/chem/lecture_04.pdf
