[ Chemistry ] Open Question : What is the final pressure in the container?

A mixture in which the mole ratio of hydrogen to oxygen is 2:1 is used to prepare water by the reaction 2H2(g) + O2 ----> 2H2O(g) The total pressure in the container is 0.950 atm at 25 degrees C before the reaction. What is the final pressure in the container at 125 degrees C after the reaction, assuming an 88.0% yield and no volume change?
