Question

A chloride of an element contain 49.5% cl if the sp heat of the element is 0.056 then the equivalent mass of element its atomic mass and molecular mass will be gh

Answer 1

the molecular mass is 5.

Answer 2

Mass of the Chlorine in the Chloride = 49.5 %

∴ Mass of the Metal = (100 - 49.5)%

   = 50.5%

∵ Equivalent Mass =  × 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

valence of the element is 3.

The mas will be 5
