Pt 1 - Glycerol (C3H8O3), 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 2.21 g glycerol dissolved in 22.00 mL ethanol (CH3CH2OH; density = 0.7893 g/mL). Round to four significant digits. Pt 2 - Use your answer to Part 2 to calculate the vapor pressure of the solution at 20°C...

500 mL, what is the molarity of the final solution?
Enter the numerical answer in decimal notation
QUESTION 10
Information - Colligative
Properties
Colligative properties of solutions are those properties which
depend only on the number of dissolved solute particles in solution
not the chemical properties of the solute. For example when a
solute is dissolved in a solvent, vapor pressure
depression...

3.32. One mole of an ideal gas, initially at 30°C and 1 bar, is changed to 130°C and 10 bar by three different mechanically reversible processes: The gas is first heated at constant volume until its temperature is 130°C; then it is compressed isothermally until its pressure is 10 bar The gas is first heated at constant pressure until its temperature is 130°C; then it is compressed isothermally to 10 bar The gas is first compressed isothermally to 10 bar;...
