Question

Equivalent weight of a metal is 9 , what will be the equivalent weight of its oxide

Answer 1

Given that

Equivalent weight of metal is 9

Find equivalent weight of its oxide

For hydrated solutions

F2Ox =equivalent weight of metal and equivalent weight of oxygen

Therefore

9+8

8 is the equivalent weight of oxygen

Therefore F2Ox is 17...............

Answer 2

Answer:

The equivalent weight of the metal oxide is 17

Explanation:

The equivalent weight of a chemical is computed by multiplying the molar mass by the number of positive or negative electrical charges produced by the component's dissolution.

In other words, the equivalent weight of a solution is equal to the solute's molecular weight divided by its valence.

That is, the equivalent weight of the Oxygen atom = $\frac{Molar Mass}{Valency}$

• Since the valency of oxygen is 2 and its molar mass is 16, the equivalent weight of the oxygen atom= $\frac{16}{2}$ = 8.

The equivalent weight of metal oxide = the sum of the equivalent weight of oxygen and metal.

It is given in the question that the equivalent weight of the metal = 9.

Therefore, the equivalent weight of the metal oxide = 9 + 8

                                                                                          = 17
