Glycerol (C_3H_8O_3), also called glycerine, is widely used in the food and pharmaceutical industries. Glycerol is polar and dissolves readily in water and polar organic solvents like ethanol. Calculate the mole fraction of the solvent in a solution that contains 1.31 g glycerol dissolved in 24.10 mL ethanol (CH_3CH_2OH: density = 0.7893 g/mL). Round to four significant digits. X_solvent = 0.9437 Use your answer to Part 2 to calculate the vapor pressure of the solution at 20 degree C if the vapor pressure of pure ethanol at this temperature is equal to 0.0575 atm. Assume that glycerol is a nonvolatile, nonelectrolyte solute. Round your answer to three significant digits. P_solution = 0.0543 atm
