CsI is an ionic crystal used in optical applications that require excellent infrared transmission at very long wavelengths (up to 55 m). It has the same crystal structure as CsCl with one Cs+ and one I- ion in the unit cell. Given the density of CsI as 4.51 g/cm3 calculate the specific heat capacity of CsI and compare it with the experimental value of 0.2 J K-1 g-1. What is your conclusion?
