The Latent Heat of sublimation for zinc(atomic mass = 65.4 u) at 600k is 1,990,000 j/kg. Assume that the zinc vapor can be treated as a monatomic ideal gas and that the volume of one kilogram of solid is negligible compared to that of the vapor. What percentage of the latent heat serves to change the internal energy during sublimation. I'm not sure what to do here. The reason why i didnt put scientific notation is because i dont like using carrots. Thanks for your help.
