Calculating saturated vapor and liquid molar volume

[nuttybred]

Hi,

I'm trying to find the pressure using the SRK equation of state at a given temperature. I'm told to use the molar volume of the pure component at the saturated state for it but I'm having a little trouble trying to find out how to calculate it given only a temperature. I'm guessing we would need to somehow find the saturated vapor pressure at that temperature and do some sort of iteration but I haven't had much luck figuring out how. Thanks for any help!
