If it says the nanostructure is made up of 64 molecules all aligned in the same direction, would W just be 64?
For part b it says they can be in any one of four orientations would n be 4 and W would be 2^4?

The formula for calculating W is (# of microstates)^#atoms/molecules. So for part a, if the nano structure is aligned in the same direction, the number of microstates is 1 and the number of molecules is 64, so W would be 1^64 which is one. For part b, the number of microstates is 4 and the number of molecules is 64, so W is 4^64.
