the vapour pressure of water at K when g of glucose is dissolved in g of water. . Henry’s law constant for the molality of methane in benzene at K is . × mm Hg.
Calculate the solubility of methane in benzene at K under mm Hg. . g of liquid A (molar mass g mol – ) was dissolved in g of liquid B (molar mass g mol – ). The vapour pressure of pure liquid B was found to be torr.
Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is Torr. . Vapour pressures of pure acetone and chloroform at K are . mm Hg and .
mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot p total , p chloroform , and p acetone as a function of x acetone . The experimental data observed for different compositions of mixture is: x x acetone . .
. p acetone /mm Hg . . .
p chloroform /mm Hg . . . .
Plot this data also on the same graph paper. Indicate whether it has positive deviation or negative deviation from the ideal solution. . Benzene and toluene form ideal solution over the entire range of composition.
The vapour pressure of pure benzene and toluene at K are . mm Hg and . mm Hg respectively. Calculate the mole fraction of benzene in vapour phase if g of benzene is mixed with g of toluene.
. The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of % is to % by volume at K . The water is in equilibrium with air at a pressure of atm.
At K if the Henry’s law constants for oxygen and nitrogen at
