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+.
After hydrogen and oxygen, the two most abundant or common elements dissolved in seawater are sodium and chloride, which combine to form salt. The salinity of seawater is measured by grams of salt per liter of water, with a typical reading of approximately 35 grams per liter, or 35 percent.
