Re: Residual Entropy

I believe it can either be J/K or J/(K*mol)

Re: Units of entropy [ENDORSED]

If the problem asks for entropy per unit of a substance, it would be J/(K*mol) or J/(K*mol) if it's per unit mass. Otherwise you can probably assume they just want the answer in J/K.

Re: 8.31 clarification

I'm pretty sure it's because the molar heat capacity is supposed to be (5/2)R which would be 20.8 J/(mol*ºC).

Homework Help 8.21

The problem states "A piece of copper of mass 20.0 g at 100.0ºC is placed in a vessel of negligible heat capacity but containing 50.7 g of water at 22.0ºC. Calculate the final temperature of the water. Assume that no energy is lost to the surroundings." I don't really know how to start thi...
