I'm just genuinely not understanding what's being asked of me here...or how to go about getting ΔS. Any insight would be much appreciated.

What equations do you know that are expression of ΔS?  And before you do any calculations, do you expect ΔS to be positive or negative for this kind of process?  Always try to conceptually understand what's going on before you plug numbers into an equation.  That way you understand what the equations mean.
