Entropy

If entropy is an intrinsic property of a system, then why is it dependent on number of particles?
Instrinsic just means essential or whatever, doesn't say anything about whether the property depends on the number of particles.

You may be confusing it with intensive, which means that the property does not depend on the size of the system.

You're right though, entropy is extensive, it depends on how much you have (although often molar entropies are discussed, which are intensive)

entropy is quoted in standard molar entropy. If you were to quote it in absolute values of entropy for a system the units would be J/K/mol not J/K
