When you have an Isothermic change in an ideal gas, you may need this formula

Another Formula is:
G_with_RT.png
When you have an problem with no change in pressure.
a formula that may work is:
delta S = n C ln(T2/T1)
C in this case is 2.5 x R
One more equation That may help
Delta S = -q/T Where q is heat and T is temperature

There is a fairly comprehensive table of Thermodynamic Quantities for Selected Substances in your book on 1058-60.


G and S Values for this unit:
