An oxygen O2 molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 196 possible sites for adsorption (see sketch at right). Calculate the entropy of this system. Round your answer to 3 significant digits, and be sure it has the correct unit symbol.
