Question

equivalent weight of CaSO4

Answer 1

Hey friend, Harish here.

Here is your answer:

We know that,

Mass of Ca = 40

Mass of S = 32.

Mass of O = 16.

Therefore their equivalent mass = 40 + 32 +  (16×4)

                                                   = 72 +  64

                                                   = 136u.
