Detailed explanation-1: -Answer: Mass of the dissolved matter in the water bodies.
Detailed explanation-2: -Sea water salinity is expressed as a ratio of salt (in grams) to liter of water. In sea water there is typically close to 35 grams of dissolved salts in each liter. It is written as 35 ‰ The normal range of ocean salinity ranges between 33-37 grams per liter (33‰-37‰).
Detailed explanation-3: -Salinity can be defined as “the concentration of dissolved mineral salts present in waters and soils on a unit volume or weight basis” (Tanji, 1990b).
Detailed explanation-4: -Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰).
Detailed explanation-5: -The term salinity refers to the amount of dissolved salts that are present in water. Sodium and chloride are the predominant ions in seawater, and the concentrations of magnesium, calcium, and sulfate ions are also substantial.
