← A student studies two liquids that form an azeotrope when mixed in one particular ratio. Which statement about this azeotrope is correct?Liquid A is six times as volatile as liquid B: its vapour pressure when pure is six times that of B at the same temperature. In an ideal solution of the two, the vapour holds A and B in equal numbers of moles. What is the mole fraction of A in the liquid? →
