## Homework Statement

Please consider ethylene at 152

^{o}F and 126 atm. Please determine the molar volume (ft

^{3}/lbmole) if Z is determined by Corresponding States Theory.

## Homework Equations

Z=PV

_{m}/R

_{m}T

V

_{m}= Molar volume

R=R

_{m}/M

M= molecular weight

R

_{m}=1545(ft*lbf)/(lbmol*

^{o}R)

Z

_{c}=(P

_{c}v

_{c})/(R*T

_{c})

T

_{c}=283 K

P

_{c}=51.2 Bar

M=28.05 Kg/Kmol

P

_{R}=P/P

_{c}

## The Attempt at a Solution

I can find V

_{c}but thats not 152

^{o}F and 126 atm.

I don't know Z at these conditions either so I can't use the other equation.
