What Is the Entropy of a Solution Containing Methane and Ethane?

[rshiku]

Homework Statement

At 25 degrees celsius and 1 atm pressure, the absolute third law entropies of methane and ethane are 186.19 J/(mol*K) and 229.49 J/(mol *K) respectively in the gas phase. Calculate the absolute third law entropies of a solution containing 1 mole of each gas. Assume Ideal gas behaviour.
