benzene has a heat of vaporization of 30.72kj/mol and a normal boiling point of 80.1c. at what temperature does benzene boil when the external pressure is 445 torr

The Clausius–Clapeyron relation is to be sued.

Tb=(R ln (Po)/deltaH - 1/To)

Po is 445torr (convert that)
To is what you are looking for
deltaHv given
Tb=80.1C convert that to K

R is universal gas constant. Watch units.
