Vapor Pressure Calculator
Formula: Vapor Pressure:
(P2) =
P1exp((ΔHv/R)(1/T1-1/T2))
Enter the unknown value as 'x'
Constant value of R = 8.3145
Vapor Pressure of Interest at T2(P2) =
atm
The Corresponding temperature(T2) =
kelvin
The Temperature at Another Point (T1) =
kelvin
Vapor Pressure at the known Temperature T1 (P1) =
atm
The Molar Enthalpy of Vaporization(Δ H) =
joule/mole
x =
