Calculate Average Molar Mass of Propane And N-Hexane Mixture

Question

A 42.0%/58.0% by volume propane/n-butane mixture is cooled from 379°C to 143°C. Find the change in enthalpy of this mixture by following the steps below. Assume ideal behavior.

a) What is the average molar mass of the mixture?

b) What is the change in specific enthalpy of pure propane from 379°C to 143°C?

c) What is the change in specific enthalpy of pure n-butane from 379°C to 143°C?

d) What is the change in specific enthalpy of the mixture from 379°C to 143°C?

e) What is the change in enthalpy of the mixture from 379°C to 143°C in kJ/kg?

Summary

The question belongs to Chemical Engineering and it discusses about calculation of average molar mass of propane and n-hexane mixture with change in specific enthalpy at different temperatures.
