The units are usually listed as Joules per Kelvin (J.K-1)

The units end up being J/K as kB = 1.381 x 10^-23 J.K^-1 and also ΔS = nRln(V2/V1) cancels out into J.K^-1.

When completing the math, usually the way the problem is set up will allow for the units to cancel out to being J/K (joules per kelvin), this can be used as another way of testing if the problem is correct!

The units are J/K, but if you forget, it could be helpful to write out the units and then see which cancel and what you're left with.

The units are Joules per Kelvin, or J/K.
