Question

$0.456\text{g}$ of a metal yielded $0.606\text{g}$ of its chloride. Calculate the equivalent mass of the metal.

• A. $91\text{g}$
• B. $61\text{g}$
• C. $31\text{g}$
• D. $108\text{g}$

Answer 1

The correct option is D $108\text{g}$

Let the equivalent weight of metal be $E$
Weight of the metal = $0.456\text{g}$
weight of the chlorine= $0.606-0.456=0.150\text{g}$
$\frac{\text{weight of the metal}}{\text{weight of chlorine}}=\frac{\text{equivalent weight of the metal}}{\text{equivalent weight of chlorine}}$
$\Rightarrow \frac{0.456}{0.150}=\frac{E}{35.5}$
On solving, $E=107.92\text{g}=108\text{g}$
