An ideal gas is taken in a container which is divided into 2 parts by a partition. Entropy of the parts is S_1 & S_2 . What will be entropy if partition is removed?

The entropy if vaporisation of benzene is 85JK^(-1) mol^(-1) . When 117g benzene vaporizes at its's normal boiling point, the entropy change in surrounding is:
