Answer: 35 grams of salt for every 1,000 grams of water

Explanation:

Salinity is the content of salt dissolved in a body of water. It is generally defined as the total amount in grams of dissolved salt contained in a kilogram (or 1000 grams) of seawater, and this is called [tex]ppt[/tex]:

[tex]1 ppt=\frac{1 g [disolved-salts]}{1000 g [seawater]}[/tex]

So, if we have a salinity of [tex]35 ppt[/tex] this is equivalent to 35 grams of disolved salts in 1000 grams of seawater:

[tex]35 ppt=\frac{35 g [disolved-salts]}{1000 g [seawater]}[/tex]

This is in fact a dimensionless value, which was defined in 1902 in this way by the amount of sodium chloride present in water as a measure of its salinity.

Answer:

35 grams of salt for every 1,000 grams of water

Explanation:

  • The basic unit of measuring seawater is considered as the parts per thousand as is said to be normal salinity places that have abnormal salinity have 40 ppt salinity of water like the red and dead sea.  
  • Salinity keeps on fluctuating and it depends on the amount of river flow, rainfall and the amount of evaporation in dry seasons.
