Question

20 g of a metal gives 100 g metal bromide on reaction with $B{r}_2$. The equivalent weight of metal is [At. wt. of Br = 80] :

• A. 40
• B. 20
• C. 80
• D. 10

Answer 1

The correct option is B 20

According to concept of equivalent mass, mass of metal combining with $80$ g of bromine is $20$. So, equivalent mass of metal = $20$ g.
