Question No.  4183 :
What is the concentration of salt in seawater?

Salinity, or "saltiness," is roughly proportional to the amount of dissolved salts in a given volume of seawater. Oceanographers report salinity in parts per thousand. In the open ocean the salt content is usually between 33 and 38 parts per thousand; average salinity throughout the world is 35 parts per thousand, i.e. 35 kg of salt per 1000 kg of seawater. Salinity includes all the dissolved material in seawater, not just the salt. The sea is about as salty as a glass of water containing a teaspoon of salt. Artificial seawater is prepared with the following major constituents: Sodium chloride 26.6 g Magnesium chloride 2.3 g Magnesium sulphate 3.3 g Calcium chloride 1.2 g Potassium chloride 0.7 g Other salts (mainly sodium bicarbonate and sodium bromide) 0.3 g Total salt 34.4 g Add water to make 1000 g Please refer to ScienceNet Question 590 for additional information.
