Question

what is the relationship between specific heat and the atomic mass of the element?

Answer 1

Equivalent weights & Atomic Weights : Equivalent weight and gram equivalent weight of an element, relation between atomic weight, eq. wt., and valency, equivalent weights of compounds (acids, bases and salts), determination of equivalent weight (hydrogen displacement method, oxide method). Determination of atomic weight based on eq. wt. & sp.heat, Calculations. involving eq/ wts. and atomic weights. 

Dulong and Petit's law : The product of atomic weight and specific heat of a solid element is 6.4 nearly. Therefore, approximate atomic weight= 6.4 / Specific heat 

A = E x V 
where A = atomic weight 
and E = equivalent weight 
V = Valency of the element
