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+.
The salinity of seawater is determined by how much freshwater enters the ocean in the form of precipitation, melting sea ice, and runoff from rivers, and how much exits through evaporation. Salinity is higher in the temperate and tropical areas where evaporation rates are higher than in polar regions.
