A 46.0%/54.0% by volume propane/n-butane mixture is cooled from255°C to 193°C. FInd the change in ethalpy of this mixture byfollowing the steps below. Assume ideal behavior. a) What is theaverage molar mass of the mixture? b) What is the change inspecific enthalpy of pure propane from 255°C to 193°C? c) What isthe change in specific enthalpy of pure n-butane from 255°C to193°C? d) What is the change in specific enthalpy of the mixturefrom 255°C to 193°C? e) What is the change in enthalpy of themixture from 255°C to 193°C in kJ/kg?
