Question

$3.0$ g of metal oxide converted to $5.0$ g of metal chloride. The equivalent weight of the metal is:

• A. $3.325$
• B. $66.50$
• C. $33.25$
• D. $25.33$

Answer 1

The correct option is C $33.25$

Since the metal oxide and chloride are involved in the same reaction, the ratio of their equivalent mass is equal to the ratio of their molecular mass.

$\frac{\text{weight of metal oxide}}{\text{weight of metallic chloride}}=$ $\frac{\text{eq. mass of metal}+eq.massof{O}^{2-}}{eq.massofmetal+eq.massofC{l}^{-}}$
Let equivalent mass of metal be $x$.
Therefore, $\frac{x+8}{x+35.5}$ $=$ $\frac{3}{5}$.
On solving, we get $x$ is equal to $33.25$ .
