Textbook question clarification

Postby Hee Sang Kim 3L » Tue Jan 26, 2016 7:17 pm

There was a textbook question asking "Calculate the change in molar entropy of an ideal gas when it is compressed isothermally to one-third its initial volume. " Is ideal gas implaying that is 1 mol of gas? How do we know the mole of gas

Well, it's asking for the molar entropy, so number of moles does not need to be specified.

When it does not specify and the gas is ideal you assume that it is 1.00 mole of gas available.
