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. Salinity refers to the proportion of dissolved salts to pure water in the ocean. The average salinity is about 35 parts per thousand. Oceanographers express salinity in parts per thousand because the proportion of dissolved substances in seawater is a very small number. 2..
