Question

The equivalent mass of a metal is double that of oxygen. How many times is the equivalent mass of its oxide greater than the mass of the metal?

• A. 2 times
• B. 1.5 times
• C. 3 times
• D. 0.5 times

Answer 1

Answer: (B)

1.5 times

The equivalent mass of oxygen is 8 .
The equivalent mass of metal is 16.
If it is a alkaline earth metal, then its molecular mass will be twice its equivalent mass.
It will be 32.
The molecular mass of metal oxide will be $32+16=48$
The equivalent mass of metal oxide will be $\frac{48}{2}=24$. It is 1.5 times that of metal.
