1-5.Two beakers, A and B, are placed in a bell jar at 298 K as illustrated below. Beaker A contains 4.00 molof pure diethyl ether which has a vapor pressure of 400 Torrand beaker B contains 2.00 molof pure pentane which has a vapor pressure of 700 Torr. Diethyl ether and pentane are miscible liquids. The bell jar is left undisturbed until the composition of the liquids in A and B no longer changes.1.The initial mole fraction of A in the vapor of the bell jar at the beginningof the period is (a)0.400 ANSWER (c) 0.364(b)0.700 (c)0.364 (d)0.636 (e)1.000 2.The initial mole fraction of B in the vapor of the bell jar at the beginningof the period is 3.The mole fraction of diethyl ether in the liquid in beaker A at the endof the waiting period is
