The N2O mole cule has the structure NUNUO. In an ordered crystal of N2O, the mol e cules are lined up in a regular fashion, with the orientation of each determined by its position in the crystal. In a random crystal (formed on rapid freezing), each mol e cule has two equally likely orientations. (a)  Calculate the number of microstates available to a ran­ dom crystal of NA (Avogadro’s number) of mol e cules. (b)  Calculate the entropy change when 1.00 mol of
