Dude.......i'm like zoning on this. I can't figure it out. I got 1.79 and .11 and .11 ...but Its not working.

Consider the following equilibrium

COBr2(g) ↔ CO(g) + Br2(g) Kc = 0.190 at 73 °C

Consider the following equilibrium:

A 3.8 mol sample of COBr2 is transferred to a 2.0 L flask and heated until equilibrium is attained. Calculate the equilibrium concentrations of each species.

[COBr2] = M

[CO] = M

[Br2] = M

And the second part of this is instead of 2L ...it's 1L and I have to find it. Does anyone know this? I'm totally stuck. I did google and ice boxed it and everything and i'm stuck. Any help?
