    The vapor pressure of ethanol is 115 torr at 34.9°C. If ΔHvap of ethanol is 38.6 kJ/mol, calculate the temperature (in °C) when the vapor pressure is 760 torr. When I plug everything in I get 1.888 = -4640 *(1/t2-3.247*10^-3) but my algebra is rusty and I don't get the same answer as the book. A detailed explanation would be greatly appreciated. Thanks! lnP2/P1= -Hvap/R*(1/t2-1/t)
