Question

The oxide of a metal has 32% oxygen. Its equivalent weight would be

• A. 34
• B. 32
• C. 17
• D. 8

Answer 1

The correct option is C 17

Let weight of metal oxide = 100gm
Weight of oxygen = 32gm
$\therefore$ weight of metal=100-32=68 gm

$E_w=W_M\times \frac{8}{{W_{O_2}}^{}}=68\times \frac{8}{32}$

$Nowequivalentweightis$

$\frac{Weightofoxide}{Weightof{O}_2}\times 8=68\times \frac{8}{32}$

$Equivalentweight\left(E_w\right)=\frac{544}{32}=17$

$Sotheequivalentweightofoxideis17$
