Use the References to access important values if needed for this question. Henry's law may be expressed in different ways and with different concentration units, resulting in different values for the Henry's law constants. If mole fraction is used as the concentration unit, one algebraic statement of the law is: Pgas KHXgas where k is the Henry's law constant in units of pressure, usually atm. . At 25°C, some water is added to a sample of gaseous krypton (Kr) at 4.37 atm pressure in a closed vessel and the vessel is shaken until as much krypton as possible dissolves. Then 3.52 kg of the solution is removed and boiled to expel the krypton, yielding a volume of 0.966 L of Kr(g) at 0°C and 1.00 atm. Determine the Henry's law constant for krypton in water based on this experiment. atm

Use the References to access important values if needed for this question. Henry's law may be expressed in different ways and with different concentration units, resulting in different values for the Henry's law constants. If mole fraction is used as the concentration unit, one algebraic statement of the law is: Pgas - KHXgas where k is the Henry's law constant in units of pressure, usually atm. At 25°C, some water is added to a sample of gaseous krypton (Kr) at 4.37 atm pressure in a closed vessel and the vessel is shaken until as much krypton as possible dissolves.

When two volatile liquids mix to form an ideal solution, both components appear in the vapor phase over the solution. Each liquid can be viewed as either the solute or the solvent, and each lowers the vapor pressure of the other. When the solution behaves ideally, Raoult's law can be used to calculate the partial pressure of each of the components over the solution. This defines the composition of the gas phase in equilibrium with the solution. At 295 K the vapor pressure of pure pentane (C5H₁2) is 0.532 atm and the vapor pressure of pure hexane (C6H14) is 0.169 atm. Equal chemical amounts (equal numbers of moles) of pentane and hexane are mixed and form an ideal solution. Compute the mole fraction of hexane in the vapor in equilibrium with this solution. Xhexane in vapor =
