Electrons Have a Property Called Spin That Can Either Be

Electrons have a property called spin that can either be up or down,analogous to how a coin can be heads or tails.Consider 6 electrons.Calculate the entropy for the case where four spins are up and two are down.

A) 1.4 * 10^-23 J/K
B) 2.2 * 10^-23 J/K
C) 1.1 * 10^-23 J/K
D) 4.6 * 10^-23 J/K
E) 3.7 * 10^-23 J/K
