I'm confused about the relationship between Boltzmann's constant and the gas constant.

R = Nk, where N is avogadro's constant and k is boltzmann's constant.

Both are used to find entropy (S), but in this class, their usage will depend on the context (info given)

The equation involving the boltzmann constant (kB), $S=k_blnW$
should be used when you're given the number of states and species,

while equations such as $\Delta S = nRln\frac{V2}{V1}$, which involve the gas constant R will be used when particular values such as volume are given
