Working this thing on Web Assign. I feel like I've been doing everything 100% correct, yet I keep getting the wrong answer.

Basically, I need help on part B and C

What I did for B, I tried to calculate Delta S by using the equation n Cv ln(T2/T1)

I plugged in Cv given in the problem, used 341 for T2, and 298 for T1. n is One, since its for one mole. And I added the value I get to delta S to S that was given in the problem.

What have I been doing wrong.
