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+.
Anyone who has ever tasted seawater knows that it is truly salty. The salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity. Salinity is a measure of how much salt is dissolved in water.The average salinity of seawater for all Earths oceans is about 35 grams of dissolved salts per kilogram of seawater. This is shown as 35 parts per thousand, or 35.he salty residue left on swimsuits after theyve been in the ocean is further evidence of the oceans salinity.
