While you're at it ... could you explain how to do part a of 28? thanks.

dS=n*R*ln(V2/V1)= Sfinal - SintialSintial = n*S = (0.1mol)*(126J/Kmol) = 12.6J/K
V1 = (n*R*T)/P1 = ((0.1mol)*(0.08206Latm/Kmol)*(298K))/1atm = 2.45L
dS= nRln(V2/V1) = (0.1mol)*(8.3145j/Kmol)*ln(5L/2.45L)= 0.593J/K
dS= Sfinal - Sintial
Sfinal = Sintial + dS = 12.6J/K + 0.593J/K = 13.2 J/K
