Explanation:
Detailed explanation-1: -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‰). But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity.
Detailed explanation-2: -Sea water is 3. 5% by mass of common salt and has a density 1. 04g cm−3 at 298K.
