Consider a solution made by dissolving 342 g of sucrose in 127 mL of water at . The vapor pressure of water at is 0.095 atm and the density of water at is 0.992 g/mL. What is the vapor pressure of the sucrose/water solution? The molar mass of sucrose is 180.2 g/mol.
The vapor pressure of pure liquid toluene at 300 K is , and the vapor pressure of pure liquid benzene at 300 K is . The mole fraction of toluene in a toluene–benzene mixture is 0.6000 and the temperature is 300 K. Assuming that mixtures of toluene and benzene behave as ideal solutions, calculate the total vapor pressure of the mixture and the mole fraction of toluene in the vapor .
Consider a 0.01 M aqueous solution of . How will the vapor pressure of this solution compare with the vapor pressure of pure liquid water?
