Question

a metal oxide contains 16%oxygen.the equivalent weight of metal is​

Answer 1

Answer:

Equivalent weight is that which combines 8 parts by oxygen . As per data oxygen 16 % metal 80%

Thus equivalent weight of mass = 32.

Depending upon a weight 1 has to find valency of metal, formula of metal sulphate and hence its equivalent weight.

Hope it will help you!

Answer 2

Given:

• The percentage of oxygen in metal oxide = 16%

To Find:

• The equivalent weight of the metal.

Solution:

The percentage of metal = 100-percentage of oxygen in metal oxide

The percentage of metal = 100-16 = 84% {subtracting the terms}

Let us take the mass of metal oxide = 100g

Therefore,

Equivalent weight of the metal = [(mass of metal)/(mass of oxygen)]*equivalent weight of oxygen  → {equation 1}

On substituting the values in equation 1 we get,

⇒ Equivalent weight of the metal = [84/16]*8 = 5.25*8

In the above step, we divided the terms in the bracket and then multiplied the remaining terms.

⇒ The equivalent weight of the metal = 42g

∴ The equivalent weight of the metal = 42g
