For a binary solution, find expressions for the mole fractions x_B and x_A as functions of the solute molality m_B.
In an azeotropic solution, the liquid and vapor phases have equal mole fractions of solute at equilibrium. Find the numerical value of the Henrt's Law coefficient that is azeotropic at its standard boiling point. Include units.
How do you find the mass percent, mole fraction, and the
molality for these two problems?
P1. (Sec. 11.1) A solution is prepared by dissolving 113 grams of acetone (C3H6O) in 662 grams of water.

1. Consider a binary solution of A and B. Assume the molar fraction of A and B in the solution is xa and Xb. The vapor pressure (in torr) of component A over the binary solution is given by: Pa = 180 - XA • exß+0.5-x} ; 0 SXA51 Determine the vapor pressure (PA) and the Henry's law constant ky,a of pure A.
Problem 1. i. There is one solution composed of solvent A and solute B. The concentration of B is given by CB, the molality is given by bb, and the density of the solution is p. If the molar mass of A and B is represented by MA and MB and the molar fraction of B in the solution is given by XB, i. derive the relation between xb and cb and xb and bb, respectively. ii. D-fructose (C6H1206) is...
An aqueous solution has a mole fraction of solute of 0.0385. What is the molality of this solution?
At 100 ?C the vapor pressures of hexane and octane are 1836 and 354 torr, respectively. A certain liquid mixture of these two compounds has a vapor pressure of 666torr at 100 ?C. Find the mole fractions in the liquid mixture and in the vapor phase. Assume an ideal solution.
If a binary mixture is an ideal solution with composition XA, and if the order parameter (in this case, composition) can be either non-conserved (allowing chemical reaction, for example), or conserved. At what composition would equilibrium be established and why, for each of the two cases?
An aqueous solution has a mole fraction of solute of 0.0385. What is the molality of this solution? (I know the answer is 2.222 m I just need help with the steps to get there)
