The equivalent weight of an element is the atomic weight of the element divided by its valency.
The atomic weight of calcium (Ca) is approximately 40.08 g/mol, and calcium typically has a valency of +2.
So, the equivalent weight of calcium (Ca) would be:
Equivalent weight = Atomic weight / Valency
Equivalent weight = 40.08 g/mol / 2
Equivalent weight = 20.04 g/mol
Rounded to the nearest whole number, the equivalent weight of calcium is 20.
So, the correct answer is D. 20.
