Question

what do you meant by salinity of seawater​

Answer 1

Answer:

Explanation:

Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

Salinity is typically measured as a concentration of grams of salt per kilogram of water (g/kg). For example, the average concentration of salt in seawater is about 35 g/kg. In other words, there are 35 grams of salt dissolved in 1 kilogram of typical seawater.
