Question

I need a detailed, step-by-step explanation. Thanks!!!

The vapor pressure of water at 20 degrees Celsius is 17.54mmHg.

a)The vapor pressure of an aqueous glucose(C₆H₁₂O₆) solution is found to be17.10mmHg. How much glucose (in grams) was added to 250mL of waterat 20 degrees Celsius to achieve this vapor pressure lowering? Thedensity of water is 1.00g/mL. Glucose is a nonvolatile solute.

b)Next we take 400mL of water (density is 1.00g/mL), and mix itwith 50mL of propanol (C₃H₈O, density is0.803g/mL). Calculate the mole fraction of propanol.

c)Propanol is a nonvolatile compound. The total vapor pressureof the water/propanol mixture in b) is 17.41mmHg at 20 degreesCelsius. Calculate the vapor pressure of propanol at 20 degreesCelsius.
