5.20 mol 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 1.40 M, where it remained constant Then, the container volume was doubled and equilibrium was re-established. How many moles of A remain? Number mol A
