Question

A chloride of an element contains 49.5% chlorine.The specific heat of the element is 0.056.Calcuate the equivalent mass,valency.

Answer 1

Hello Dear.

Here is the answer---


Mass of the Chlorine in the Chloride = 49.5 %
∴ Mass of the Metal = (100 - 49.5)%
   = 50.5%

∵ Equivalent Mass = $\frac{Mass of the Metal}{Mass of the Chlorine}$ × 35.5
= (50.5/49.5) × 35.5
= 36.21 

∴ Equivalent mass is 36.21

For the Valency,
 
∵ Atomic Mass of the Element × Specific Heat = 6.4
∴ Atomic mass of the Element = 6.4/0.056
= 114.28

∵ Valency = Atomic Mass/Equivalent Mass
   = 114.28/36.21
   = 3.16
   ≈ 3

∴ Valency of the Element is 3.


Hope it helps.

Answer 2

Answer:

equivalent mass= 36

valency=3
