At 20C, the vapour pressure of ethanol is 45.0 torr and the vapour pressure of methanol is 92.0 torr. What is the vapour pressure at 20C of a solution prepared by mixing 62.9g of methanol and 54.2g of ethanol? Psolution= torr Question 2 A solution contains 2.4 mol water, 0.32 mol sucrose (C12H22O11), and 0.47 mol of glucose. Sucrose-and glucose are nonvolatile. a. What is the mole fraction of water in this solution? water= b. What is the vapor pressure of the solution at 35C, given the-vapor pressure of water at 35C is 37 torr. Psolution=
