Chemistry

A 46.0%/54.0% by volume propane/n-butane mixture is cooled from255Â°C to 193Â°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 255Â°C to 193Â°C? c) What isthe change in specific enthalpy of pure n-butane from 255Â°C to193Â°C? d) What is the change in specific enthalpy of the mixturefrom 255Â°C to 193Â°C? e) What is the change in enthalpy of themixture from 255Â°C to 193Â°C in kJ/kg?

Dear Student 1 Average Molar Mass of the mixture is calculated as follows Molar mass of propane is 4401 gmoles Molar mass of nbutane is 5812 gmoles Therefore average molar mass of the mixture is m 46 x 4401 54 x 5812 m 046 x 4401 054 x 5812 m 2024 3138 m 2024 3138 m 5162 Hence the average molar mass of the mixture See Answer
