1. The problem statement, all variables and given/known data Suppose a compound could point in any two directions in the solid and still have the same energy. How many molecules would there be if the total entropy of a solid sample of this compound was 1.181x10^-12 J/K? 2. Relevant equations My plan that failed - S = k*ln(W), where S is entropy k is Boltzman constant = 1.38 x 10-23 (J/K) or equivalent to (Universal Gas Constant 8.314/Avogadro's number 6.02 x 1023 molecules/mol) W is the number of microstates 3. The attempt at a solution 1.181x10^-12 J/K = (8.314/ x 6.02*1023)*(ln(2)), I put 2 in ln(2) because I thought the question stated the total microstates when it said "...point in any two directions". I solved for x and got 3.242e13 which is wrong.
