A 40.0-L container is divided into two equal parts by a rubber membrane. One half of the container has 1.80 moles of an ideal monatomic gas at 270 K, and the other half is a vacuum

The container does not allow any gas to escape but is free to exchange heat with the surroundings. The membrane breaks, the gas expands isothermally and eventually the gas reaches a new equilibrium condition occupying the entire volume. What is the change in entropy of the gas? A) 10.4 J/K
B) 9.16 J/K
C) 12.5 J/K
D) 14.3 J/K
E) 16.4 J/K
