What is the equivalent weight of hydride of metal if equivalent weight of its oxide is 20?

Explanation

To find the equivalent weight of the hydride of a metal when the equivalent weight of its oxide is given as 20, we can follow these steps:

### Step 1: Understand the relationship between the equivalent weight of the metal oxide and the metal.
The equivalent weight of a metal oxide can be expressed as:
\[ \text{Equivalent weight of metal oxide} = \text{Equivalent weight of metal} + \text{Equivalent weight of oxygen} \]
Given that the equivalent weight of the metal oxide is 20, we can write:
