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.
