A certain liquid has a vapor pressure of 92.0 Torr at 23.0 °C and 313.0 Torr at 45.0 °C. Calculate the value of ΔH°vap for this liquid.
Calculate the normal boiling point of this liquid.
How would I do this? Please help

Best ResponseYou've already chosen the best response.1I used \[\log\frac{ P2 }{ P1 }=\frac{ ΔH }{2.303R }*(\frac{ 1? }{ T1 }\frac{ 1 }{ T2 })\]
