Clausius Clapeyron equation:

ln(P1/P1) = ∆Hvap/R (1/T2 - 1/T1)

P1 = 425 torr

T1 = 25 + 273 = 298K

P2 = 760 torr

T2 = 50.2+273 = 323.2

R = 8.314

∆Hvap = ?

ln(425/760) = ∆H/R (1/323.2 - 1/298)

-0.581 = ∆H/8.314 (0.003096 - 0.00356)

-0.581 =∆H/8.314 (-0.000464)

-4.830/-0.000464 = ∆H

∆Hvap = 10,410 J = 10.4 kJ
