A mixture of A and B has a liquid-vapor phase diagram as shown in the picture which is not ideal. Assume that 1.5 mol of A and 3.5 mol of B were mixed in an isothermal vessel. Then equilibration was done, and the total vapor pressure was determined to be 50.0 torr. Solve for the number of moles of B that is present in the vapor phase. Choose your answer. a. 1.43 mol b. 1.07 mol c. 1.82 mol d. 2.43 mol
