# Problem: If a system has 1×1015 ways of arranging its energy, what will its entropy be?

###### FREE Expert Solution

Recall that we can use the Boltzmann Equation to determine the entropy given the number of microstates:

$\overline{){\mathbf{S}}{\mathbf{=}}{{\mathbf{K}}}_{{\mathbf{B}}}{\mathbf{lnW}}}$

where:

S = entropy

KB = Boltzmann constant (1.38 x 10–23 J/K)

W = number of microstates
