A43.0%/57.0% by volume propane/n-butane mixture is cooled from 367°c to 163°c. flnd the change in ethalpy of this mixture by following the steps below. assume ideal behavior a) what is the average molar mass of the mixture? number g/mol b) what is the change in specific enthalpy of pure propane from 367°c to 163°c? number kj/ mol c) what is the change in specific enthalpy of pure n-butane from 367°c to 163 c? number kj/ mol
d) what is the change in specific enthalpy of the mixture from 367°c to 163°c? number kj/ mol e) what is the change in enthalpy of the mixture from 367°c to 163'c in kj/kg? number kj/ kg
