Self Test 9.2

Self-Test 9.3A Calculate the change in molar entropy of an ideal gas when it is compressed isothermally to one-third its initial volume.

So far, I can see that you use the equation deltaS=nRln(V2/V1), but what would you use for n in this case?

Since they're asking for molar entropy (by definition the entropy at one mole of substance), n would simply be 1.
