Part #1:
30.0 g of glucose (C6H12O6, molar mass = 180.16 g/mol) are dissolved in 100. grams of water (molar mass 18.02). What is the mole fraction of water in solution? Note: glucose is a non-volatile solute.
Part #2:
At 25.0 oC, pure water has a vapor pressure of 24.2 torr. What would the vapor pressure of the solution in part one be (in torr)?
Part #3:
A liquid is a mixture of benzene and toluene. The sample contains 0.225 moles of benzene and 0.775 moles of toluene. At a given temperature, pure benzene has a vapor pressure of 38.02 torr, while pure toluene has a vapor pressure of 8.73 torr. What is the total combined vapor pressure of the two liquids (in torr?)?
