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

    Should you use Clausius-Clapeyron equation?

    do I just solve for T2 and use the same values?

    Well, let the normal boiling point be T2

    wouldn't that just give me the T that is given in the question ?

    I used \[\log\frac{ P2 }{ P1 }=\frac{ ΔH }{2.303R }*(\frac{ 1? }{ T1 }-\frac{ 1 }{ T2 })\]
