Deterining Entropy of Vaporization of Methanol?

Question

Appreicate it if someone could show me how to work the following problem: Thanks alot!

Knowing that the label for entropy is J/mol K determine the entropy of vaporization of methanol. THe boiling point of methanol, CH3OH, is 64.6 degrees C and the enthalphy of vaporization is 35.21 mol.


(K = C + 273)

Answer 1

It's all there in the question for you.

DeltaS (what you want) = q/T

enthalpy is surely 35.21 J/mol, not 35.21 mol. That is your q per mol.

T = 273 + 64.6.

That's all!
