Question

Weight of metal and chlorine in a metal chloride are
in 1 : 5 mass ratio. The equivalent weight of the
metal will be
(1) 14.2
(2) 7.1
(3) 24
(4) 5​

Answer 1

Answer:

12.08

Explanation:

Let the mass of the metallic chloride be x

.: Mass of the chlorine in the Metallic

chloride = 74. 73 % of x.

= 0. 7473x

Also, Mass of the Metal in the chloride

= Mass of the metallic Chloride - Mass

of the Chlorine in the Metallic Chloride

Mass of the metal = x - 0. 7473x

.: Mass of the Metal = 0. 2527x

Now, Using the Formula,

Equivalent weight of the metal = Mass

of the Metal/ Mass of the Chlorine) *

Molar Mass of the Chlorine.

.. Equivalent Weight of the Metal =

(0. 2527x/ 0. 7473x) x 35. 5

[: * Atomic Mass of the chlorine is 35. 5)

.. Equivalent Weight of the Metal =

0. 338 x 35. 5

.: Equivalent weight of the Metal =12.08
