The standard enthalpy of vaporization for CHF2Cl is 233.59 J/g at its normal boiling point of -40.75°C. 

Calculate the standard entropy of vaporization (ΔS°vap) of CHF2Cl(l)

Answer to the nearest 0.1 J K-1 mol-1.

Again, we use G = H - TS

H = 233.59 J/g

T = -40.75 + 273 = 232.25 K

 G = 0

So essentially we have H = TS, solving for S....

S = H / T = (233.59 J/g) / (232.25 K) =

 1.0 J/K/g
