A container is divided into two equal volumes by a very thin membrane. It is held at a fixed temperature by immersion in a water bath. The left half holds 1.1 mol of gas, and the right half holds 2.2 mol of the same gas. The membrane is then punctured so that gas can flow freely between the two sides. What is the change in the entropy of the system after the gas has come to equilibrium? Express your answer with the appropriate units. AS = Value Units ?
