Categories: Water

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 599 mM), which is a specific gravity of about 1.025. 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+) and chloride (Cl−) ions).
