MCQ
One gram of hydrogen is found to combine with $80\,g$ of bromine one gram of calcium valency $=2$ combines with $4\,g$ of bromine the equivalent weight of calcium is
- A$10$
- ✓$20$
- C$40$
- D$80$
✓
Answer
Correct option: B.
$20$
b
(b) One gram of hydrogen combines with $80\,gm $ of bromine.
(b) One gram of hydrogen combines with $80\,gm $ of bromine.
So, equivalent weight of bromine $= 80\,gm$
$4\,gm$ of bromine combines with $1\,gm$ of $Ca$
$\therefore $ $80\,gm$ of bromine combines with = $\frac{1}{4} \times 80 = 20$.
