Two beakers are placed in a small closed container at $25C.$ One contains $486mL$ of a $0\mathrm{.}130M$ aqueous solution of $N{H}_{2}CON{H}_2$; the second contains $281mL$ of a $0\mathrm{.}269M$ aqueous solution of $N{H}_{2}CON{H}_2.$ Small amounts of water evaporate from both solutions. As time passes, the volume of solution in the second beaker gradually and that in the first gradually $.$ If we wait long enough, what will the final volumes and concentrations be$?$
