Question

How to calculate molar mass from specific heat?

Answer 1

It can be done by Dulongs and petit’s law.

But it give approximate value -

Dulong and Petit’s law says that, for a given solid element, …

molar mass (M) (g/mol) x specific heat (c) (J/g.K) = 25 J/mol. K

Assume the specific heat units are Joules/g K .
