Using Dulong and Petit's law, what will be the atomic mass of metal having specific heat capacity 0.1344 JK`^(-1)gm^(-1)`

A

47.62 gm/mol

B

840 gm/mol

C

100 gm/mol

D

200 gm/mol

Text Solution

Verified by Experts

Specific heat (Cal/mole-K: atomic mass `approx6.4`
`(0.1344)/(4.2)xx` atomic mass `approx6.4`
Atomic mass `approx=(6.4xx4.2)/(0.1344)=200 gm//"mol"`
