Thermodynamics Part 2

A container is divided into two chambers by a partition. The volume of first chamber is 4.5L and second chamber is 5.5L. The first chamber contain 3.0mol of gas at pressure 2.0atm and second chamber contain 4.0mol of gas at pressure 3.0atm. After the partition is removed and the mixture attains equilibrium, then the common equilibrium pressure existing in the mixture is x×10−1 atm. Value of x is .......... .
