# Final che205 notes1 ```Before finishing the question check this list:
1234-
Units are correct!!!! And make sure to include time /s /h /min
Make sure it’s not remaining!
Equations:
Clausius-Clapeyron:
Ln[P1/P2] = [Hvap/R]*[1/T2-1/T1]
R = 8.314 J/mol K
Hvap will be in Joules/mol
T = Kelvin
Antoine Equation:
Log10(P*)= A- (B/(C+T))
Log10(P*) = P*= 10^(A-B/(C+T))
For conversion:
1 lb-mole * (454g/1lb) = gmol = mol
(1 lb-mole/454mol)
To calculate a volume of a liquid
Volume of the liquid = Vcontainer-Vgas
Volume of gas: (which can be found using IDGEOS plugging vapor pressure and number of moles of vapor )
SCMH = standard cubic meter/hour
SCFM = standard cubic ft/min
Hydrogen and Helium correction factor:
Tc + 8k
Pc + 8atm
To get absolute pressure always add 1 atm to the Gauge pressure.
To get moles fraction of vapor to liquid, divide vapor pressure by absolute pressure of the container
SRK is the most accurate but only applies to limited set of pure species.
For SRK use 0.08206 units will cancel out
Kay’s Rule/Compressibility factor is the only option for gas mixtures
When you do DOF
