50 points) a gas stream containing n-hexane in nitrogen with a relative saturation of 90% is fed to a condenser at 75 oc and 3 atm absolute. the product gas emerges at 0 oc and 3 atm at a rate of 746.7 m3/h. calculate the percentage condensation of hexane (moles condensed/moles fed), and the rate (kw) at which heat must be transferred from the condenser. (final -730 to -750 kw)
