I am in chemistry 1, and trying to determine an unknown volatile
liquid. I have the boiling point (give or take 3 degrees celsius)
which is 85.0 degrees celsius. I also have the molecular weight
(give or take 10g/mol) to be 61.05g/mol. Here are pictures of the
Infra red spectrophotometry graph which I was told is basically the
finger print of a substance. Do you know what substance this
volatile liquid is?

The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid...
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure P and temperature T is expressed by the Clausius-Clapeyron equation. lnP2P1=ΔHvapR(1T1−1T2) where P1 and P2 are the vapor pressures at the absolute temperatures T1 and T2, respectively, ΔHvap is the heat of vaporization of the substance in joules per mole, and R is the ideal gas constant, which is equal to 8.3145 J/(mol⋅K)....
