Imagine that one carbon in buckminsterfullerene (c60) is replaced by a silicon atom, yielding sic59. this molecule can then orient in 60 different ways. what is the entropy of one mole of sic59 at t = 0 k?

The entropy will be 0

Explanation:

Because of the third principle of thermodynamics, the entropy of a pure substance (such as SiC59), with finite density (we have 1 mol in a finite volume), at 0 K is equal to 0.

So, it really dosen't mather the Si atom, if you are analizing it at the absolute zero (0 K).
