The molar heat capacity at 25°C should be close to 27 J/K-mol for all of the given elements except

Options:

Answer:
C
Solution:

Solid metals follow the Dulong-Petit value 3R ≈ 25 J/K-mol (Pt, W and Sr are all about 24 to 27). Ne is a monatomic gas with Cp = 5/2R = 20.8 J/K-mol (Cv = 12.5), far from 27. So the exception is (c).
