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, or 600 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+.
1 Detailed composition: abundance of the elements in seawater. 2  Salinity: the main salt ions making the sea salty. 3  Density: the density of sea water depends on temperature and salinity. 4  Dissolved gases: the two important gases to life, oxygen and carbondioxide.as molecule % in atmosphere % in surface seawater ml/litre sea water mg/kg (ppm) in sea water molecular weight mmol/ kg Nitrogen N2 78% 47.5% 10 12.5 28.014 0.446 Oxygen O2 21% 36.0% 5 7 31.998 0.219 Carbondioxide CO2 0.03% 15.1% 40 90 * 42.009 2.142 Argon 1% 1.4% .
