Question

The carbonate of a metal contains $50$% metal, the equivalent mass of metal atom would be:

• A. $15$
• B. $30$
• C. $50$
• D. $25$

Answer 1

The correct option is B $30$

$MC{O}_3⟹$weight of $M=$ weight of $C{O}_3$

Mass of metal$=50g$.

Mass of carbonate$=50g$.

$50g$ of metal$=50g$ of carbonate

$30g$ of metal$=30g$ of carbonate

Hence, equivalent weight of carbonate and metal is $30$.
