Hello, is it possible to figure out how much force in newtons is created when a compressed gas expands?

Without more details, no.

Pressure drop? Not sure what that is :( Volume expansion is twice the original volume

More or less what he said.

When a gas is contained by some closed surface, the surface doesn't move because there is a force balance between the inside and ouside of the container. If you want, you could calculae the hydrostatic force exerted by the gas by integrating the pressure over the surface (which usually just amounts to multiplying the pressure by the area). But without a lot more details, it isn't clear how one would calculate the force on an expanding gas container. If it's a simple system like a piston, then the problem is fairly easy. For more complex systems...well, you'd have to give me a few more specific details before I could solve the problem.
