Question

When a metal is burnt, its weight is increased by $24$ percent. The equivalent weight of the metal will be:

• A. 2
• B. 24
• C. 33.3
• D. 76

Answer 1

The correct option is C 33.3

The equivalent weight of $O^2$ is $\frac{16}{2}=8g$

now one equivalent of metal reacts with one equivalent of oxygen

Let equivalent weight of metal be $X$ which reacts with 8g of oxygen

$X=\frac{8\times 100}{24}=33.3g$
