SUMMARY
The entropy of a solution containing 1 mole of methane and 1 mole of ethane at 25 degrees Celsius and 1 atm pressure can be calculated using the absolute third law entropies of each gas, which are 186.19 J/(mol*K) for methane and 229.49 J/(mol*K) for ethane. Assuming ideal gas behavior, the entropy of mixing must be considered to determine the total entropy of the solution. The concept of entropy of mixing is crucial for solving this problem effectively.
