HW 5-6: Question 5

[Shaniya Kerns 4D]

The molar heat capacity for carbon monoxide at constant volume is Cv,m = 20.17 J/(K-mol).
A 4.00-L fixed-volume flask contains CO(g) at a pressure of 5.00 kPa and a temperature of 25.0 °C.
Assuming that carbon monoxide acts as an ideal gas and that its heat capacity is constant over the given temperature range,
calculate the change in entropy for the gas when it is heated to 800.0 °C.

Entropy=?
After I have found the mols, what are the next steps in finding the entropy?
n=0.00807 mol

I found the answer to be 0.5937! I used the formula delta S = Cvln(T2/T1).
