Question

Calculate the molar heat capacity of a monatomic non-metallic solid at 298K which is characterized by an Einstein temperature of 2000K. Express your result as a multiple of 3R.

Answer 1

Answer: 5.5 ×10^-2 ×3R. Non metals that are solid at room temperature has mono atomic atoms that has only 3 translational modes.

This is why their constant volume molar heat capacities are measured in multiples of 3R.
