Given:

Specific heat = 1 J/gK

= 0.22 cal/g/mol

Equivalent weight = 9

By using Dulong Petit law,

Approximate atomic mass = 6.4 / Specific heat

=6.4/ 0.22

= 29.09 g

Valency = Approximate atomic mass / Equivalent weight

= 29.09 / 9

= 3.23

=3

Exact atomic weight = Equivalent weight × Valency

= 9× 3

= 27

Exact atomic weight of metal is 27 g.
