Consider the equilibrium
H2(g) + Br2(g) 2HBr(g)
To a 20.0 L flask are added 0.100 moles of H2 and 0.200 moles of HBr. The equilibrium constant for this reaction is 989. Calculate the number of moles of Br2 in the flask when equilibrium is established. Make any reasonable approximation, clearly stating what that approximation is.
