When calculating the entropy change due to the change in temperature, where does the the equation delta S = n R ln (t2/t1) come from in the solutions manual? Shouldn't the equation be delta S = n C ln(t2/t1)? And how are we supposed to assume that there are 1.00 moles of N2 gas without the problem explicitly stating it?
Since this question asks you to assume that the N2 exhibits ideal gas behavior, the variation of the entropy equation S= nRln(T2/T1). Additionally, since the question mentions that the gas is ideal and no number of moles is otherwise specified, the number of moles in the container is implied to be 1 mole. For more information on this, refer to pg. 323.
