What is the correct sequence of the following salts in ascending order according to their presence in the sea water? 1. Calcium Carbonate 2. Calcium Sulphate 3. Magnesium Chloride Select the answer using the code given below :

The concentration of dissolved salts in sea water in ascending order is: Calcium Carbonate (about 0.3%), Calcium Sulphate (about 3.6%), and Magnesium Chloride (about 4.7%) of the total dissolved salts. The most abundant salt in seawater is Sodium Chloride (about 77%), followed by Magnesium Chloride, Magnesium Sulphate, Calcium Sulphate, and Calcium Carbonate. Therefore, in ascending order: Calcium Carbonate < Calcium Sulphate < Magnesium Chloride, giving the sequence 1, 2, 3.
