This question says: Consider a process in which an ideal gas is compressed to one-eighth of its original volume at constant temperature. Calculate the entropy change per mole of gas.
I know the equation is delta S=nRln(v2/v1) but how do i find n, the number of moles?

I'm not positive that this is correct. However, I think since it says per mole of gas and the number of moles aren't given, you can assume that n=1.

I don't think you need need to find the number of moles since the question is asking for ∆S/n not ∆S.

In this case, you don't necessarily need to look for the number of moles, since the unit of measure of entropy is J(mol*K), so n=1. Naturally, solve for everything else the way you're supposed to and you'll get the correct answer.

Re: Sapling #4
If one-eight in the problem was stated as one-fifth would the problem be set up similarly?
