What is the Equivalent Weight of Calcium Carbonate

Answer. 50 

The equivalent weight of Calcium Carbonate (CaCO3) can be measured are as follows: 

Equivalent weight = Molecular weight / Valency 

The molecular weight of CaCO3 = 100 

Valency of CaCO3 = +2

Equivalent weight = 100/2 

                                = 50 (Equivalent weight)
