Question

Equivalent weight of ca in caco3

Answer 1

It is not equivalent mass but equvalent weight.

Equivalent weight = molecular weight of compound ÷ charge on compound.

Molecular weight of CaCO3 (calcium carbonate):

Atomic weight of calcium+ atomic weight of carbon + atomic weight of oxygen.

Atomic weight of Calcium : 40

Atomic weight of Carbon :12

Atomic weight of Oxygen:16

So, 40+12+16(3)= 100

Charge on CaCO3 = ca^2+ + CO3^2-

Charge = 2.

So equivalent weight of CaCO3 = 100÷2

Equivalent weight of CaCO3 =50

Answer 2

Answer:

Equivalent mass of Ca in CaCO3 = 50g.

Explanation:

The equivalent mass of CaCO3 is 100g/2=50g. Thus,The equivalent mass of Calcium Carbonate is 50g.
