64 grams of methanol at a temperature of \[60{}^\circ C\]are poured into 128 gram of methanol kept at \[20{}^\circ C\]in an insulated vessel. Calculate the net change in entropy that occurs. (give your answer in J/K and in the form of nearest whole number) \[Cp\] (methanol) =81.6 J/K-mol [log(0.9198) =-0.036; log (1.045) = 0.0193]
