Question

What is milliequivalent weight of calcium carbonate?

Answer 1

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
