Question

equivalent weight of gypsum ​

Answer 1

Answer:

Equivalent weight of Gypsum will be 86 grams per equivalent.

Explanation:

As the molecular formula of gypsum is CaSO4 . 1/2 H20

Formula :

Equivalent weight = Molecular mass / nf

where nf = total no. of charges

As it has 1 atom of calcium and 1 ion of sulfate, it will have nf of 2.

By putting the values in above formula:

Equivalent weight = 172 / 2

Equivalent weight = 86 grams per equivalent

So,

 Equivalent weight of Gypsum will be 86 grams per equivalent.
