Physics: pressure of mixing gases

[Blair12]

Homework Statement

96 grams of oxygen and 50 grams of hydrogen gas occupy separate, equal sections of 200 liter tank. The divide is removed and the gases are allowed to mix and react with each other. Temperature is kept constant at 120 degrees celsius
2. Homework Equations [/B]
b) find the pressure after the reaction ends

The Attempt at a Solution

I was able to get part A, which was finding the pressure in their separate containers but am not sure how to do part b.
