A solid element has a specific heat of `1 Jg^(-1) K^(-1)`. The atomic mass of the element is

A

9

B

18

C

27

D

36

Text Solution

Verified by Experts

The correct Answer is:
C
We know Atomic mass= `(6.4)/("sp. Heat (in calories)")`
Also 4.184 J = `~~` 1 calorie
1J=0.239 cal `~~` 0.24 cal `g^(-1) k^(-1)`
Atomic mass =6.4/0.24 =26.77 `~~`27.0
