Attempt 4 a 5.60 mol sample of solid a was placed in a sealed 1.00 l container and allowed to decompose into gaseous b and c. the concentration of b steadily increased until it reached 1.10 m, where it remained constant. a(s)↽−−⇀b(g)+c(g) then, the container volume was doubled and equilibrium was re‑established. how many moles of a remain?
