Question

One g of hydrogen is found to combine with 80 g of bromine. One g of calcium (valency = 2) combines with 4 g of bromine. The equivalent weight of calcium is

(a) 10

(b) 20

(c) 40

(d) 80

Answer 1

Correct option is (b) 20

Gram eq. wt. of bromine = 80g

Gram eq. wt. of calcium = \(\frac{1 \times 80}4\) = 20 g
