Question

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?

Answer 1

Given:

NaCl Composition of sea water = 35%

Cl- composition = 55%

To determine:

The amount of Cl- ions i grams in sea water

Step-by-step explanation:

Based on the data:

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.
