Question

Equivalent mass metal is $12$. Hence, equivalent mass of its oxide is:

• A. $24$
• B. $28$
• C. $20$
• D. $34$

Answer 1

The correct option is C $20$

Given: Equivalent mass metal =12

Solution :

Equivalent mass of oxygen = $\frac{Molarmass}{nfactor}=\frac{16}{2}=8$

Therefore, Equivalent mass of metal oxide = Equivalent mass of metal + equivalent mass of oxygen

$\Rightarrow Equivalentmassofmetaloxide=12+8=20$

Hence, correct option is C.
