Question

What is the equivalent weight of oxide of a metal if equivalent weight of metal chloride is 58.5?​

Answer 1

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) × 35.5

[∵ Atomic Mass of the chlorine is 35.5]

∴ Equivalent Weight of the Metal = 0.338 × 35.5

∴ Equivalent weight of the Metal = 12.004

Hence, the Equivalent weight of the metal in the metallic chloride is 12.004.

Hope it helps.
