Solution

The correct option is A 20
When as per given the ratioof Ca and Br combined is 1:4 by mass
So according to this
Ca+Br2CaBr2
20 g 80 g

Note: 20/80=1/4,
20 g is the half molar wt of Ca and 80 g is molar wt. of Br.
Now as valency of Ca is 2.
So equivalent weight of Ca = 40 /2 = 20 .

(option B)
