For a system of molecules, T = 300 K, q = 1E30, and \(\Delta U = 3740 J/mol\). What is the molar entropy if the molecules are distinguishable, and if they are indistinguishable?

Attempt:

For distinguishable: S/n = R ln q + U/T = 586.8 J/(K mol), which is correct

For indistinguishable: I've learnt that q' = q/N! in this case, but this number is practically zero. That would mean S/n = approaches infinity. The correct answer is 139.9 J/(K mol)
