Since seawater salinity is 35‰, or 3.5%, 1000 grams of seawater contains 35 grams of salt. cl - represents 55% of the dissolved component in seawater. how is this number expressed in grams?

Given:

NaCl Composition of sea water = 35%

Cl - composition = 55%

To determine:

The amount of Cl - ions i grams in sea water

Explanation:

Based on the dа ta:

1000 g of sea water contains 35 g of NaCl

It is given that Cl - composition is 55% of that of salt (NaCl)

Therefore, amount of dissolved Cl - = 55/100 * 35 = 19.25 g

Ans: 19.25 g of Cl - represents the dissolved component in sea water.
